also it has occurred to me that i dont even need to do that first timestamp overlap check. i literally have a file where i recorded start and stop times for each dataset. damn
#tütensuppe#oh well#though i might have to adjust it some i forgot what method i used to calculate those times#if i did it as datetime/timedelta addition its fine if i used timestamps itll have the same float problem#maybe i can avoid memory issues if i build numpy arrays right away rather than saving things in a list..

so my wife (@beaniebaby492) has a problem that maybe some of my mutuals can help with. she's wanting a data structure with these qualities: -fast reading of slices of numpy (or similar) arrays -scalable between ~10Gb - 1Tb (largest data reaches Pb but rarely and can always be reduced easily) -ideally easy to move to a computing cluster if computations become too expensive -some way to include metadata -easy to convert to just standard numpy/pandas for when data is mostly processed and reduced
side note. these are mostly a sequence of 3D arrays given different experimental parameters
she's "leaning towards dask and xarray with h5 data structure since it is somewhat commonly used in [her] field"
what would y'all recommend?

liveblogging my descent into madness over this lab report i’ve been procrastinating because what else can ya do to cope
10:22 PM — got Pandas working to read all my data into Python. do not like working with pd dataframes instead of numpy arrays but when you have 100,000 data points you take what you can get
this mfer is due 1 PM tomorrow so it’s an all-nighter (or near it) for me. rly wish i didn’t live with my (anti-alcohol) parents because i feel like a glass of wine would greatly improve my nerves about this situation but i suppose a honey cinnamon coffee will do
#uncertain ramblings#really should remember that tag exists more often#not everyone is here to hear me groan about my real life lol

Working on a Python project for weeks and I'm adamant we use Numpy. I'm new to numpy, and my partner knows no Python. I'm convinced this'll be super efficient because Numpy is good.
We can't get Numpy to work, we spend weeks getting everything working and nothing is working.
We end up getting rid of all of it and using standard Python arrays.
Make more progress in one night than we did in weeks.
I was a gigantic asshat for insisting we do something a certain way. Legitimately detrimental to doing what we need to do. Now that the professor and my partner are working on it because this went from a class assignment to a potential research paper. (Worth noting that we couldn't have succeeded without assistance from the professor so he's cool) everything I contributed has been removed at the end of the day except wasting weeks of sleepless nights and it's specifically and unequivocally at my hands.
I feel stupid and asshattish and as if I owe someone something. I'm acting defensive and I shouldn't because they're right when they say that this should be done in the easy straightforward way.
I feel like lashing out and I can't do that. I'm aware I'm in the wrong. I was wrong and I'm angry that it feels like I'm a prick

Financial Modeling in the Age of AI: Skills Every Investment Banker Needs in 2025
In 2025, the landscape of financial modeling is undergoing a profound transformation. What was once a painstaking, spreadsheet-heavy process is now being reshaped by Artificial Intelligence (AI) and machine learning tools that automate calculations, generate predictive insights, and even draft investment memos.
But here's the truth: AI isn't replacing investment bankers—it's reshaping what they do.
To stay ahead in this rapidly evolving environment, professionals must go beyond traditional Excel skills and learn how to collaborate with AI. Whether you're a finance student, an aspiring analyst, or a working professional looking to upskill, mastering AI-augmented financial modeling is essential. And one of the best ways to do that is by enrolling in a hands-on, industry-relevant investment banking course in Chennai.
What is Financial Modeling, and Why Does It Matter?
Financial modeling is the art and science of creating representations of a company's financial performance. These models are crucial for:
Valuing companies (e.g., through DCF or comparable company analysis)
Making investment decisions
Forecasting growth and profitability
Evaluating mergers, acquisitions, or IPOs
Traditionally built in Excel, models used to take hours—or days—to build and test. Today, AI-powered assistants can build basic frameworks in minutes.
How AI Is Revolutionizing Financial Modeling
The impact of AI on financial modeling is nothing short of revolutionary:
1. Automated Data Gathering and Cleaning
AI tools can automatically extract financial data from balance sheets, income statements, or even PDFs—eliminating hours of manual entry.
2. AI-Powered Forecasting
Machine learning algorithms can analyze historical trends and provide data-driven forecasts far more quickly and accurately than static models.
3. Instant Model Generation
AI assistants like ChatGPT with code interpreters, or Excel’s new Copilot feature, can now generate model templates (e.g., LBO, DCF) instantly, letting analysts focus on insights rather than formulas.
4. Scenario Analysis and Sensitivity Testing
With AI, you can generate multiple scenarios—best case, worst case, expected case—in seconds. These tools can even flag risks and assumptions automatically.
However, the human role isn't disappearing. Investment bankers are still needed to define model logic, interpret results, evaluate market sentiment, and craft the narrative behind the numbers.
What AI Can’t Do (Yet): The Human Advantage
Despite all the hype, AI still lacks:
Business intuition
Ethical judgment
Client understanding
Strategic communication skills
This means future investment bankers need a hybrid skill set—equally comfortable with financial principles and modern tools.
Essential Financial Modeling Skills for 2025 and Beyond
Here are the most in-demand skills every investment banker needs today:

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.
