How you can use python for data wrangling and analysis

Python is a powerful and versatile programming language that can be used for various purposes, such as web development, data science, machine learning, automation, and more. One of the most popular applications of Python is data analysis, which involves processing, cleaning, manipulating, and visualizing data to gain insights and make decisions.

In this article, we will introduce some of the basic concepts and techniques of data analysis using Python, focusing on the data wrangling and analysis process. Data wrangling is the process of transforming raw data into a more suitable format for analysis, while data analysis is the process of applying statistical methods and tools to explore, summarize, and interpret data.

To perform data wrangling and analysis with Python, we will use two of the most widely used libraries: Pandas and NumPy. Pandas is a library that provides high-performance data structures and operations for manipulating tabular data, such as Series and DataFrame. NumPy is a library that provides fast and efficient numerical computations on multidimensional arrays, such as ndarray.

We will also use some other libraries that are useful for data analysis, such as Matplotlib and Seaborn for data visualization, SciPy for scientific computing, and Scikit-learn for machine learning.

To follow along with this article, you will need to have Python 3.6 or higher installed on your computer, as well as the libraries mentioned above. You can install them using pip or conda commands. You will also need a code editor or an interactive environment, such as Jupyter Notebook or Google Colab.

Let’s get started with some examples of data wrangling and analysis with Python.

Example 1: Analyzing COVID-19 Data

In this example, we will use Python to analyze the COVID-19 data from the World Health Organization (WHO). The data contains the daily situation reports of confirmed cases and deaths by country from January 21, 2020 to October 23, 2023. You can download the data from here.

First, we need to import the libraries that we will use:import pandas as pd import numpy as np import matplotlib.pyplot as plt import seaborn as sns

Next, we need to load the data into a Pandas DataFrame:df = pd.read_csv('WHO-COVID-19-global-data.csv')

We can use the head() method to see the first five rows of the DataFrame:df.head()

Date_reportedCountry_codeCountryWHO_regionNew_casesCumulative_casesNew_deathsCumulative_deaths2020–01–21AFAfghanistanEMRO00002020–01–22AFAfghanistanEMRO00002020–01–23AFAfghanistanEMRO00002020–01–24AFAfghanistanEMRO00002020–01–25AFAfghanistanEMRO0000

We can use the info() method to see some basic information about the DataFrame, such as the number of rows and columns, the data types of each column, and the memory usage:df.info()

Output:

RangeIndex: 163800 entries, 0 to 163799 Data columns (total 8 columns): # Column Non-Null Count Dtype — — — — — — — — — — — — — — — 0 Date_reported 163800 non-null object 1 Country_code 162900 non-null object 2 Country 163800 non-null object 3 WHO_region 163800 non-null object 4 New_cases 163800 non-null int64 5 Cumulative_cases 163800 non-null int64 6 New_deaths 163800 non-null int64 7 Cumulative_deaths 163800 non-null int64 dtypes: int64(4), object(4) memory usage: 10.0+ MB “><class 'pandas.core.frame.DataFrame'> RangeIndex: 163800 entries, 0 to 163799 Data columns (total 8 columns): # Column Non-Null Count Dtype --- ------ -------------- ----- 0 Date_reported 163800 non-null object 1 Country_code 162900 non-null object 2 Country 163800 non-null object 3 WHO_region 163800 non-null object 4 New_cases 163800 non-null int64 5 Cumulative_cases 163800 non-null int64 6 New_deaths 163800 non-null int64 7 Cumulative_deaths 163800 non-null int64 dtypes: int64(4), object(4) memory usage: 10.0+ MB

We can see that there are some missing values in the Country_code column. We can use the isnull() method to check which rows have missing values:df[df.Country_code.isnull()]

Output:

Date_reportedCountry_codeCountryWHO_regionNew_casesCumulative_casesNew_deathsCumulative_deaths2020–01–21NaNInternational conveyance (Diamond Princess)WPRO00002020–01–22NaNInternational conveyance (Diamond Princess)WPRO0000……………………2023–10–22NaNInternational conveyance (Diamond Princess)WPRO07120132023–10–23NaNInternational conveyance (Diamond Princess)WPRO0712013

We can see that the missing values are from the rows that correspond to the International conveyance (Diamond Princess), which is a cruise ship that had a COVID-19 outbreak in early 2020. Since this is not a country, we can either drop these rows or assign them a unique code, such as ‘IC’. For simplicity, we will drop these rows using the dropna() method:df = df.dropna()

We can also check the data types of each column using the dtypes attribute:df.dtypes

Output:Date_reported object Country_code object Country object WHO_region object New_cases int64 Cumulative_cases int64 New_deaths int64 Cumulative_deaths int64 dtype: object

We can see that the Date_reported column is of type object, which means it is stored as a string. However, we want to work with dates as a datetime type, which allows us to perform date-related operations and calculations. We can use the to_datetime() function to convert the column to a datetime type:df.Date_reported = pd.to_datetime(df.Date_reported)

We can also use the describe() method to get some summary statistics of the numerical columns, such as the mean, standard deviation, minimum, maximum, and quartiles:df.describe()

Output:

New_casesCumulative_casesNew_deathsCumulative_deathscount162900.000000162900.000000162900.000000162900.000000mean1138.300062116955.14016023.4867892647.346237std6631.825489665728.383017137.25601215435.833525min-32952.000000–32952.000000–1918.000000–1918.00000025%-1.000000–1.000000–1.000000–1.00000050%-1.000000–1.000000–1.000000–1.00000075%-1.000000–1.000000–1.000000–1.000000max -1 -1 -1 -1

We can see that there are some negative values in the New_cases, Cumulative_cases, New_deaths, and Cumulative_deaths columns, which are likely due to data errors or corrections. We can use the replace() method to replace these values with zero:df = df.replace(-1,0)

Now that we have cleaned and prepared the data, we can start to analyze it and answer some questions, such as:

Which countries have the highest number of cumulative cases and deaths?

How has the pandemic evolved over time in different regions and countries?

What is the current situation of the pandemic in India?

To answer these questions, we will use some of the methods and attributes of Pandas DataFrame, such as:

groupby() : This method allows us to group the data by one or more columns and apply aggregation functions, such as sum, mean, count, etc., to each group.

sort_values() : This method allows us to sort the data by one or more

loc[] : This attribute allows us to select a subset of the data by labels or conditions.

plot() : This method allows us to create various types of plots from the data, such as line, bar, pie, scatter, etc.

Mastering NumPy in Python – The Ultimate Guide for Data Enthusiasts

Imagine calculating the average of a million numbers using regular Python lists. You’d need to write multiple lines of code, deal with loops, and wait longer for the results. Now, what if you could do that in just one line? Enter NumPy in Python, the superhero of numerical computing in Python.

NumPy in Python (short for Numerical Python) is the core package that gives Python its scientific computing superpowers. It’s built for speed and efficiency, especially when working with arrays and matrices of numeric data. At its heart lies the ndarray—a powerful n-dimensional array object that’s much faster and more efficient than traditional Python lists.

What is NumPy in Python and Why It Matters

Why is NumPy a game-changer?

It allows operations on entire arrays without writing for-loops.

It’s written in C under the hood, so it’s lightning-fast.

It offers functionalities like Fourier transforms, linear algebra, random number generation, and so much more.

It’s compatible with nearly every scientific and data analysis library in Python like SciPy, Pandas, TensorFlow, and Matplotlib.

In short, if you’re doing data analysis, machine learning, or scientific research in Python, NumPy is your starting point.

The Evolution and Importance of NumPy in Python Ecosystem

Before NumPy in Python, Python had numeric libraries, but none were as comprehensive or fast. NumPy was developed to unify them all under one robust, extensible, and fast umbrella.

Created by Travis Oliphant in 2005, NumPy grew from an older package called Numeric. It soon became the de facto standard for numerical operations. Today, it’s the bedrock of almost every other data library in Python.

What makes it crucial?

Consistency: Most libraries convert input data into NumPy arrays for consistency.

Community: It has a huge support community, so bugs are resolved quickly and the documentation is rich.

Cross-platform: It runs on Windows, macOS, and Linux with zero change in syntax.

This tight integration across the Python data stack means that even if you’re working in Pandas or TensorFlow, you’re indirectly using NumPy under the hood.

Setting Up NumPy in Python

How to Install NumPy

Before using NumPy, you need to install it. The process is straightforward:

bash

pip install numpy

Alternatively, if you’re using a scientific Python distribution like Anaconda, NumPy comes pre-installed. You can update it using:

bash

conda update numpy

That’s it—just a few seconds, and you’re ready to start number-crunching!

Some environments (like Jupyter notebooks or Google Colab) already have NumPy installed, so you might not need to install it again.

Importing NumPy in Python and Checking Version

Once installed, you can import NumPy using the conventional alias:

python

import numpy as np

This alias, np, is universally recognized in the Python community. It keeps your code clean and concise.

To check your NumPy version:

python

print(np.__version__)

You’ll want to ensure that you’re using the latest version to access new functions, optimizations, and bug fixes.

If you’re just getting started, make it a habit to always import NumPy with np. It’s a small convention, but it speaks volumes about your code readability.

Understanding NumPy in Python Arrays

The ndarray Object – Core of NumPy

At the center of everything in NumPy lies the ndarray. This is a multidimensional, fixed-size container for elements of the same type.

Key characteristics:

Homogeneous Data: All elements are of the same data type (e.g., all integers or all floats).

Fast Operations: Built-in operations are vectorized and run at near-C speed.

Memory Efficiency: Arrays take up less space than lists.

You can create a simple array like this:

python

import numpy as np arr = np.array([1, 2, 3, 4])

Now arr is a NumPy array (ndarray), not just a Python list. The difference becomes clearer with larger data or when applying operations:

python

arr * 2 # [2 4 6 8]

It’s that easy. No loops. No complications.

You can think of an ndarray like an Excel sheet with superpowers—except it can be 1d, 2d, 3d, or even higher dimensions!

1-Dimensional Arrays – Basics and Use Cases

1d arrays are the simplest form—just a list of numbers. But don’t let the simplicity fool you. They’re incredibly powerful.

Creating a 1D array:

python

a = np.array([10, 20, 30, 40])

You can:

Multiply or divide each element by a number.

Add another array of the same size.

Apply mathematical functions like sine, logarithm, etc.

Example:

python

b = np.array([1, 2, 3, 4]) print(a + b) # Output: [11 22 33 44]

This concise syntax is possible because NumPy performs element-wise operations—automatically!

1d arrays are perfect for:

Mathematical modeling

Simple signal processing

Handling feature vectors in ML

Their real power emerges when used in batch operations. Whether you’re summing elements, calculating means, or applying a function to every value, 1D arrays keep your code clean and blazing-fast.

2-Dimensional Arrays – Matrices and Their Applications

2D arrays are like grids—rows and columns of data. They’re also the foundation of matrix operations in NumPy in Python.

You can create a 2D array like this:

python

arr_2d = np.array([[1, 2, 3], [4, 5, 6]])

Here’s what it looks like:

lua

[[1 2 3] [4 5 6]]

Each inner list becomes a row. This structure is ideal for:

Representing tables or datasets

Performing matrix operations like dot products

Image processing (since images are just 2D arrays of pixels)

Some key operations:

python

arr_2d.shape # (2, 3) — 2 rows, 3 columns arr_2d[0][1] # 2 — first row, second column arr_2d.T # Transpose: swaps rows and columns

You can also use slicing just like with 1d arrays:

python

arr_2d[:, 1] # All rows, second column => [2, 5] arr_2d[1, :] # Second row => [4, 5, 6]

2D arrays are extremely useful in:

Data science (e.g., CSVS loaded into 2D arrays)

Linear algebra (matrices)

Financial modelling and more

They’re like a spreadsheet on steroids—flexible, fast, and powerful.

3-Dimensional Arrays – Multi-Axis Data Representation

Now let’s add another layer. 3d arrays are like stacks of 2D arrays. You can think of them as arrays of matrices.

Here’s how you define one:

python

arr_3d = np.array([ [[1, 2], [3, 4]], [[5, 6], [7, 8]] ])

This array has:

2 matrices

Each matrix has 2 rows and 2 columns

Visualized as:

lua

[ [[1, 2], [3, 4]],[[5, 6], [7, 8]] ]

Accessing data:

python

arr_3d[0, 1, 1] # Output: 4 — first matrix, second row, second column

Use cases for 3D arrays:

Image processing (RGB images: height × width × color channels)

Time series data (time steps × variables × features)

Neural networks (3D tensors as input to models)

Just like with 2D arrays, NumPy’s indexing and slicing methods make it easy to manipulate and extract data from 3D arrays.

And the best part? You can still apply mathematical operations and functions just like you would with 1D or 2D arrays. It’s all uniform and intuitive.

Higher Dimensional Arrays – Going Beyond 3D

Why stop at 3D? NumPy in Python supports N-dimensional arrays (also called tensors). These are perfect when dealing with highly structured datasets, especially in advanced applications like:

Deep learning (4D/5D tensors for batching)

Scientific simulations

Medical imaging (like 3D scans over time)

Creating a 4D array:

python

arr_4d = np.random.rand(2, 3, 4, 5)

This gives you:

2 batches

Each with 3 matrices

Each matrix has 4 rows and 5 columns

That’s a lot of data—but NumPy handles it effortlessly. You can:

Access any level with intuitive slicing

Apply functions across axes

Reshape as needed using .reshape()

Use arr.ndim to check how many dimensions you’re dealing with. Combine that with .shape, and you’ll always know your array’s layout.

Higher-dimensional arrays might seem intimidating, but NumPy in Python makes them manageable. Once you get used to 2D and 3D, scaling up becomes natural.

NumPy in Python Array Creation Techniques

Creating Arrays Using Python Lists

The simplest way to make a NumPy array is by converting a regular Python list:

python

a = np.array([1, 2, 3])

Or a list of lists for 2D arrays:

python

b = np.array([[1, 2], [3, 4]])

You can also specify the data type explicitly:

python

np.array([1, 2, 3], dtype=float)

This gives you a float array [1.0, 2.0, 3.0]. You can even convert mixed-type lists, but NumPy will automatically cast to the most general type to avoid data loss.

Pro Tip: Always use lists of equal lengths when creating 2D+ arrays. Otherwise, NumPy will make a 1D array of “objects,” which ruins performance and vectorization.

Array Creation with Built-in Functions (arange, linspace, zeros, ones, etc.)

NumPy comes with handy functions to quickly create arrays without writing out all the elements.

Here are the most useful ones:

np.arange(start, stop, step): Like range() but returns an array.

np.linspace(start, stop, num): Evenly spaced numbers between two values.

np.zeros(shape): Array filled with zeros.

np.ones(shape): Array filled with ones.

np.eye(N): Identity matrix.

These functions help you prototype, test, and create arrays faster. They also avoid manual errors and ensure your arrays are initialized correctly.

Random Array Generation with random Module

Need to simulate data? NumPy’s random module is your best friend.

python

np.random.rand(2, 3) # Uniform distribution np.random.randn(2, 3) # Normal distribution np.random.randint(0, 10, (2, 3)) # Random integers

You can also:

Shuffle arrays

Choose random elements

Set seeds for reproducibility (np.random.seed(42))

This is especially useful in:

Machine learning (generating datasets)

Monte Carlo simulations

Statistical experiments.

Reshaping, Flattening, and Transposing Arrays

Reshaping is one of NumPy’s most powerful features. It lets you reorganize the shape of an array without changing its data. This is critical when preparing data for machine learning models or mathematical operations.

Here’s how to reshape:

python

a = np.array([1, 2, 3, 4, 5, 6]) b = a.reshape(2, 3) # Now it's 2 rows and 3 columns

Reshaped arrays can be converted back using .flatten():

python

flat = b.flatten() # [1 2 3 4 5 6]

There’s also .ravel()—similar to .flatten() but returns a view if possible (faster and more memory-efficient).

Transposing is another vital transformation:

python

matrix = np.array([[1, 2], [3, 4]]) matrix.T # Output: # [[1 3] # [2 4]]

Transpose is especially useful in linear algebra, machine learning (swapping features with samples), and when matching shapes for operations like matrix multiplication.

Use .reshape(-1, 1) to convert arrays into columns, and .reshape(1, -1) to make them rows. This flexibility gives you total control over the structure of your data.

Array Slicing and Indexing Tricks

You can access parts of an array using slicing, which works similarly to Python lists but more powerful in NumPy in Python.

Basic slicing:

python

arr = np.array([10, 20, 30, 40, 50]) arr[1:4] # [20 30 40]

2D slicing:

python

mat = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) mat[0:2, 1:] # Rows 0-1, columns 1-2 => [[2 3], [5 6]]

Advanced indexing includes:

Boolean indexing:

python

arr[arr > 30] # Elements greater than 30

Fancy indexing:

python

arr[[0, 2, 4]] # Elements at indices 0, 2, 4

Modifying values using slices:

python

arr[1:4] = 99 # Replace elements at indices 1 to 3

Slices return views, not copies. So if you modify a slice, the original array is affected—unless you use .copy().

These slicing tricks make data wrangling fast and efficient, letting you filter and extract patterns in seconds.

Broadcasting and Vectorized Operations

Broadcasting is what makes NumPy in Python shine. It allows operations on arrays of different shapes and sizes without writing explicit loops.

Let’s say you have a 1D array:

python

a = np.array([1, 2, 3])

And a scalar:

python

b = 10

You can just write:

python

c = a + b # [11, 12, 13]

That’s broadcasting in action. It also works for arrays with mismatched shapes as long as they are compatible:

python

a = np.array([[1], [2], [3]]) # Shape (3,1) b = np.array([4, 5, 6]) # Shape (3,)a + b

This adds each element to each element b, creating a full matrix.

Why is this useful?

It avoids for-loops, making your code cleaner and faster

It matches standard mathematical notation

It enables writing expressive one-liners

Vectorization uses broadcasting behind the scenes to perform operations efficiently:

python

a * b # Element-wise multiplication np.sqrt(a) # Square root of each element np.exp(a) # Exponential of each element

These tricks make NumPy in Python code shorter, faster, and far more readable.

Mathematical and Statistical Operations

NumPy offers a rich suite of math functions out of the box.

Basic math:

python

np.add(a, b) np.subtract(a, b) np.multiply(a, b) np.divide(a, b)

Aggregate functions:

python

np.sum(a) np.mean(a) np.std(a) np.var(a) np.min(a) np.max(a)

Axis-based operations:

python

arr_2d = np.array([[1, 2, 3], [4, 5, 6]]) np.sum(arr_2d, axis=0) # Sum columns: [5 7 9] np.sum(arr_2d, axis=1) # Sum rows: [6 15]

Linear algebra operations:

python

np.dot(a, b) # Dot product np.linalg.inv(mat) # Matrix inverse np.linalg.det(mat) # Determinant np.linalg.eig(mat) # Eigenvalues

Statistical functions:

python

np.percentile(a, 75) np.median(a) np.corrcoef(a, b)

Trigonometric operations:

python

np.sin(a) np.cos(a) np.tan(a)

These functions let you crunch numbers, analyze trends, and model complex systems in just a few lines.

NumPy in Python  I/O – Saving and Loading Arrays

Data persistence is key. NumPy in Python lets you save and load arrays easily.

Saving arrays:

python

np.save('my_array.npy', a) # Saves in binary format

Loading arrays:

python

b = np.load('my_array.npy')

Saving multiple arrays:

python

np.savez('data.npz', a=a, b=b)

Loading multiple arrays:

python

data = np.load('data.npz') print(data['a']) # Access saved 'a' array

Text file operations:

python

np.savetxt('data.txt', a, delimiter=',') b = np.loadtxt('data.txt', delimiter=',')

Tips:

Use .npy or .npz formats for efficiency

Use .txt or .csv for interoperability

Always check array shapes after loading

These functions allow seamless transition between computations and storage, critical for real-world data workflows.

Masking, Filtering, and Boolean Indexing

NumPy in Python allows you to manipulate arrays with masks—a powerful way to filter and operate on elements that meet certain conditions.

Here’s how masking works:

python

arr = np.array([10, 20, 30, 40, 50]) mask = arr > 25

Now mask is a Boolean array:

graphql

[False False True True True]

You can use this mask to extract elements:

python

filtered = arr[mask] # [30 40 50]

Or do operations:

python

arr[mask] = 0 # Set all elements >25 to 0

Boolean indexing lets you do conditional replacements:

python

arr[arr < 20] = -1 # Replace all values <20

This technique is extremely useful in:

Cleaning data

Extracting subsets

Performing conditional math

It’s like SQL WHERE clauses but for arrays—and lightning-fast.

Sorting, Searching, and Counting Elements

Sorting arrays is straightforward:

python

arr = np.array([10, 5, 8, 2]) np.sort(arr) # [2 5 8 10]

If you want to know the index order:

python

np.argsort(arr) # [3 1 2 0]

Finding values:

python

np.where(arr > 5) # Indices of elements >5

Counting elements:

python

np.count_nonzero(arr > 5) # How many elements >5

You can also use np.unique() to find unique values and their counts:

python

np.unique(arr, return_counts=True)

Need to check if any or all elements meet a condition?

python

np.any(arr > 5) # True if any >5 np.all(arr > 5) # True if all >5

These operations are essential when analyzing and transforming datasets.

Copy vs View in NumPy in Python – Avoiding Pitfalls

Understanding the difference between a copy and a view can save you hours of debugging.

By default, NumPy tries to return views to save memory. But modifying a view also changes the original array.

Example of a view:

python

a = np.array([1, 2, 3]) b = a[1:] b[0] = 99 print(a) # [1 99 3] — original changed!

If you want a separate copy:

python

b = a[1:].copy()

Now b is independent.

How to check if two arrays share memory?

python

np.may_share_memory(a, b)

When working with large datasets, always ask yourself—is this a view or a copy? Misunderstanding this can lead to subtle bugs.

Useful NumPy Tips and Tricks

Let’s round up with some power-user tips:

Memory efficiency: Use dtype to optimize storage. For example, use np.int8 instead of the default int64 for small integers.

Chaining: Avoid chaining operations that create temporary arrays. Instead, use in-place ops like arr += 1.

Use .astype() For type conversion:

Suppress scientific notation:

Timing your code:

Broadcast tricks:

These make your code faster, cleaner, and more readable.

Integration with Other Libraries (Pandas, SciPy, Matplotlib)

NumPy plays well with others. Most scientific libraries in Python depend on it:

Pandas

Under the hood, pandas.DataFrame uses NumPy arrays.

You can extract or convert between the two seamlessly:

Matplotlib

Visualizations often start with NumPy arrays:

SciPy

Built on top of NumPy

Adds advanced functionality like optimization, integration, statistics, etc.

Together, these tools form the backbone of the Python data ecosystem.

Conclusion

NumPy is more than just a library—it’s the backbone of scientific computing in Python. Whether you’re a data analyst, machine learning engineer, or scientist, mastering NumPy gives you a massive edge.

Its power lies in its speed, simplicity, and flexibility:

Create arrays of any dimension

Perform operations in vectorized form

Slice, filter, and reshape data in milliseconds

Integrate easily with tools like Pandas, Matplotlib, and SciPy

Learning NumPy isn’t optional—it’s essential. And once you understand how to harness its features, the rest of the Python data stack falls into place like magic.

So fire up that Jupyter notebook, start experimenting, and make NumPy your new best friend.

Mastering NumPy Broadcasting for Efficient Computation 

If you're working with Python for data science, you've probably come across NumPy, a powerful library for handling numerical data. One of NumPy’s standout features is broadcasting, which simplifies operations on arrays of different shapes without requiring manual adjustments. This not only enhances computational efficiency but also improves memory management, making it a must-know technique for data scientists and machine learning professionals. 

In this guide, we’ll break down NumPy broadcasting, explaining how it works and why it’s a game-changer for high-performance computing. We’ll also explore real-world applications and discuss how you can master these skills through the Online Data Science Course UAE. 

Why Does NumPy Broadcasting Matter? 

When working with large datasets, efficiency is crucial. Traditional element-wise operations require arrays to have the same dimensions, which can lead to increased memory usage and slower execution times. Broadcasting eliminates this limitation by allowing NumPy to automatically adjust smaller arrays, ensuring they align with larger ones without duplicating data. 

Key Advantages of Broadcasting: 

Faster computations: Eliminates the need for explicit looping. 

Optimized memory usage: Avoids unnecessary copies of data. 

Simplifies code: Enhances readability by removing manual reshaping. 

Understanding How NumPy Broadcasting Works 

To apply broadcasting, NumPy follows a set of rules when performing operations on arrays of different shapes: 

If the arrays have different dimensions, NumPy expands the smaller array by adding singleton dimensions (size 1) from the left until both arrays have the same number of dimensions. 

If dimensions differ, those with size 1 are stretched to match the corresponding dimension of the larger array. 

If the arrays are still incompatible, a ValueError is raised. 

Example 1: Adding a Scalar to an Array 

import numpy as np    matrix = np.array([[1, 2, 3], [4, 5, 6]])  # Shape (2,3)  scalar = 10  # Shape ()    result = matrix + scalar  print(result) 

Output:  [[11 12 13]  [14 15 16]] 

Here, the scalar is automatically expanded to match the shape of the array, enabling efficient element-wise addition. 

Example 2: Broadcasting a 1D Array to a 2D Array 

matrix_2d = np.array([[1, 2, 3], [4, 5, 6]])  # Shape (2,3)  vector = np.array([10, 20, 30])  # Shape (3,)    result = matrix_2d + vector  print(result) 

Output:  [[11 22 33]  [14 25 36]] 

NumPy expands the 1D array across rows to match the (2,3) shape, allowing seamless element-wise operations. 

Example 3: Multi-Dimensional Broadcasting 

array_3d = np.array([[[1], [2], [3]]])  # Shape (1,3,1)  array_2d = np.array([[10, 20, 30]])  # Shape (1,3)    result = array_3d + array_2d  print(result) 

Output:  [[[11 21 31]    [12 22 32]    [13 23 33]]] 

NumPy stretches the shapes to align properly and executes the addition efficiently. 

Real-World Applications of NumPy Broadcasting 

1. Speeding Up Machine Learning Workflows 

Broadcasting is heavily used in data normalization for training machine learning models. Instead of manually reshaping arrays, NumPy allows quick transformations: 

data = np.array([[50, 60, 70], [80, 90, 100]])  mean = np.mean(data, axis=0)  norm_data = (data - mean) / np.std(data, axis=0) 

This efficiently normalizes the dataset without unnecessary loops. 

2. Image Processing 

Broadcasting is widely applied in image manipulation, such as adjusting brightness levels across RGB channels: 

image = np.random.rand(256, 256, 3)  # A 256x256 RGB image  brightness = np.array([1.2, 1.1, 0.9])  adjusted_image = image * brightness 

Each colour channel is scaled independently, improving computational efficiency. 

3. Financial & Statistical Analysis 

In financial modeling, broadcasting simplifies calculations like percentage change computations: 

prices = np.array([100, 102, 105, 110])  returns = (prices[1:] - prices[:-1]) / prices[:-1] * 100 

This eliminates manual looping, making stock price analysis faster and more efficient.
