Lists in python
Lists in Python are a type of sequence data type. They are mutable, meaning that they can be changed after they are created. Lists can store elements of any type, including strings, integers, floats, and even other lists.
Lists are represented by square brackets ([]) and contain elements separated by commas. For example, the following code creates a list of strings:
Python
my_list = ["apple", "banana", "cherry"]
Lists can be accessed using indices, which start at 0. For example, the following code prints the first element of the list my_list:
Python
print(my_list[0])
Output:
apple
Lists can also be sliced, which allows you to extract a subset of the list. For example, the following code prints a slice of the list my_list that contains the first two elements:
Python
print(my_list[0:2])
Output:
['apple', 'banana']
Lists can be modified by adding, removing, or changing elements. For example, the following code adds an element to the end of the list my_list:
Python
my_list.append("orange")
The following code removes the first element of the list my_list:
Python
my_list.pop(0)
The following code changes the second element of the list my_list:
Python
my_list[1] = "pear"
Lists can be used to perform a variety of tasks, such as storing data, iterating over data, and performing data analysis.
Here are some examples of how to use lists in Python:
Python
# Create a list of numbers numbers = [1, 2, 3, 4, 5] # Print the list print(numbers) # Add an element to the list numbers.append(6) # Remove an element from the list numbers.pop(0) # Sort the list numbers.sort() # Reverse the list numbers.reverse() # Iterate over the list for number in numbers: print(numbers)
Output:
[1, 2, 3, 4, 5] [2, 3, 4, 5, 6] [3, 4, 5, 6] [6, 5, 4, 3] 3 4 5 6
Lists are a powerful tool for working with collections of data in Python. They can be used to perform a variety of tasks, such as storing data, iterating over data, and performing data analysis.

What Is a Dynamically Typed Language?
When learning Python, you might hear the term “dynamically typed language” frequently. But what does it mean? Let’s break it down.
Typing refers to type-checking—the process of verifying whether the data types in your code are compatible with the operations being performed.
1️⃣ Strongly vs. Weakly Typed Languages
Strongly-Typed Languages (e.g., Python): These languages don’t allow type-coercion (implicit type conversion). For example:
pythonCopy code"1" + 2 # TypeError: cannot concatenate 'str' and 'int'
Weakly-Typed Languages (e.g., JavaScript): These languages allow type-coercion:
javascriptCopy code"1" + 2 // Outputs: "12"
2️⃣ Static vs. Dynamic Typing
Type-checking can occur at two stages:
Static Typing (e.g., Java, C++): Data types are checked before the program runs. You must declare the type of variables explicitly:
javaCopy codeintx=10;
Dynamic Typing (e.g., Python): Data types are checked during program execution. Variable types are inferred automatically:
pythonCopy codex = 10 # No need to declare 'x' as an integer.
Python: A Dynamically Typed Language
Since Python is an interpreted language, it executes code line by line. Type-checking happens on the fly, allowing you to write flexible and concise code.
Example: pythonCopy codex = "Hello"x = 10 # No error—Python allows 'x' to change types.
This flexibility makes Python beginner-friendly but also increases the risk of runtime errors if types are misused.
Key Takeaway
Dynamic typing simplifies coding by removing the need for explicit type declarations. However, it also requires careful testing to ensure type-related bugs don’t creep in.
Python learners, embrace dynamic typing—it’s one of the reasons Python is so versatile and fun to use!

Introduction to Python
Python is a widely used general-purpose, high level programming language. It was initially designed by Guido van Rossum in 1991 and developed by Python Software Foundation. It was mainly developed for emphasis on code readability, and its syntax (set of rules that govern the structure of a code) allows programmers to express concepts in fewer lines of code.
Python is a programming language that lets you work quickly and integrate systems more efficiently.
data types: Int(integer), float(decimal), Boolean(True or False), string, and list; variables, expressions, statements, precedence of operators, comments; modules, functions-- - function and its use, flow of execution, parameters and arguments.
Programming in python
To start programming in Python, you will need an interpreter. An interpreter is basically a software that reads, translates and executes the code line by line instead of combining the entire code into machine code as a compiler does.
Popular interpreters in python
Cpython
Jython
PyPy
IronPython
MicroPython
IDEs
Many other programmers also use IDEs(Integrated Development Environment) which are softwares that provide an extensive set of tools and features to support software development.
Examples of IDEs
Pycharm
Visual studio code (VS code)
Eclipse
Xcode
Android studio
Net beans

What is a Python variable?
A Python variable is a symbolic name that references or points to a value stored in memory. Variables are used to store data that can be manipulated and referenced throughout a program. In Python, you don't need to declare the type of variable explicitly; instead, you simply assign a value to it using the equals (=) sign. For example, x = 10 creates a variable x that holds the value 10. Variables can store various data types, such as integers, strings, or lists.

Python Basics: Casting, Input, Operators & Formatting
Starting with Python but confused by how to handle user input or print results? You’re not alone!
If you're just beginning your coding journey, terms like type casting, input, operators, and string formatting might sound intimidating. But they’re actually easy to understand once you see them in action.
This beginner-friendly guide on tumblr.com breaks down these four essentials with real examples, clear explanations, and zero jargon. By the end, you'll know how to interact with users, perform operations, convert data types, and format your output beautifully.
Let’s get started!
What is Type Casting in Python?
Type casting is the process of changing a value from one data type to another. For example, converting a string to an integer, or an integer to a string.
🧠 Analogy: Imagine you're cooking a recipe that needs 100 milliliters of milk, but you only have a measuring cup in liters. You’ll need to convert it to the right unit—just like Python needs to convert types for certain tasks.
When Do You Use Type Casting?
You’ll often need it when dealing with user input, which is always received as a string—even if the user enters a number.
Example:
pythonCopy
Edit
age = "25" age = int(age) # Type casting from string to integer print(age + 5) # Output: 30
Without type casting, age + 5 would result in an error.
Safe Casting with Try-Except (Optional):
Sometimes, the input isn’t valid. This is how you avoid program crashes:
pythonCopy
Edit
try: age = int(input("Enter your age: ")) print(age + 5) except ValueError: print("Please enter a valid number.")
Getting User Input
Python’s input() function lets you interact with users by asking them for information.
Basic Example:
pythonCopy
Edit
name = input("What’s your name? ") print(f"Hello, {name}!")
Whatever the user types is stored as a string.
So if someone types 27, Python still sees it as "27".
Combine Input with Casting:
pythonCopy
Edit
age = int(input("Enter your age: ")) print(f"In 5 years, you'll be {age + 5}.")
Here’s what’s happening:
User types a number.
It’s stored as a string.
We convert it to an integer using int().
We use math and print the result.
Now your program is interactive and intelligent!
Understanding Operators in Python
Operators are symbols that let you perform actions like math, comparisons, and logic.
Think of them as tools—each has a different purpose.
Main Categories of Python Operators:
1. Arithmetic Operators
pythonCopy
Edit
a = 10 b = 3 print(a + b) # 13 print(a - b) # 7 print(a * b) # 30 print(a / b) # 3.333... print(a // b) # 3 (floor division) print(a % b) # 1 (modulus) print(a ** b) # 1000 (10 to the power of 3)
2. Assignment Operators
Used to assign or update values:
pythonCopy
Edit
x = 5 x += 3 # Same as x = x + 3 print(x) # Output: 8
Other examples: -=, *=, /=, etc.
3. Comparison Operators
Used to compare values:
pythonCopy
Edit
print(5 == 5) # True print(5 != 3) # True print(10 > 6) # True print(4 <= 4) # True
4. Logical Operators
Used for combining conditions:
pythonCopy
Edit
x = 10 y = 5 print(x > y and y < 10) # True print(x < y or y == 5) # True print(not(x == y)) # True
These are super useful in if statements and loops!
String Formatting in Python
String formatting makes your output cleaner and easier to read. It’s how you insert variables into sentences.
Let’s look at three ways to do it:
1. String Concatenation
pythonCopy
Edit
name = "Alice" print("Hello " + name)
Easy, but gets messy with numbers or longer messages.
2. Using format() Method
pythonCopy
Edit
name = "Bob" print("Hello, {}".format(name))
Great for inserting multiple variables:
pythonCopy
Edit
age = 30 print("Hello, {}. You are {} years old.".format(name, age))
3. f-Strings (Best for Python 3.6+)
pythonCopy
Edit
name = "Chris" age = 28 print(f"Hello, {name}. You are {age} years old.")
f-Strings are clean, powerful, and easier to read.
Bonus: Decimal Formatting
pythonCopy
Edit
price = 49.99 print(f"Total: ${price:.2f}") # Output: Total: $49.99
This is great for displaying prices or percentages.
Small Project: All Concepts Together
Let’s bring it all into one mini project!
pythonCopy
Edit
name = input("Enter your name: ") age = int(input("Enter your age: ")) future = age + 10 print(f"{name}, you’ll be {future} in 10 years!")
Try it out!
Change the age range.
Use more string formatting.
Add more logic (like checking if age > 18).
This tiny program uses everything we've learned:
✅ Python input and output ✅ Python type casting ✅ Python operators explained ✅ Python string formatting
Conclusion
Congrats! 🎉 You've just learned four key concepts in Python:
Type Casting: Convert values to the right data type.
User Input: Make your program interactive.
Operators: Perform math, comparisons, and logic.
String Formatting: Create clean, dynamic output.
These are the building blocks of Python programming.
💡 Tip: Save this post to your tumblr.com blog or bookmark it for quick reference whenever you need a refresher. And don’t forget to share it with fellow beginners who might be struggling with these exact topics.
Keep experimenting, and happy coding! 🐍
FAQs
What is type casting in Python and how do I use it?
Type casting converts one data type into another—like turning a string "42" into an integer 42 using int(). It’s commonly used when handling user input.
What is the best way to get user input in Python?
Use the built-in input() function. Always remember that it returns a string, so use int() or float() if you need numeric values.
pythonCopy
Edit
number = int(input("Enter a number: "))
What’s the difference between = and == in Python?
= is the assignment operator (used to assign values to variables).
== is the comparison operator (used to check if two values are equal).
Which is better for formatting strings: format() or f-strings?
f-Strings are better for most situations—they're simpler, faster, and more readable. Use them if you’re using Python 3.6 or later.
Why does Python input always return a string?
Because Python doesn’t know if you want a number, word, or symbol. It returns everything as a string so you can decide what to do next (cast it to int, float, etc.).

Interning in python, what is it.
Python uses a technique called interning to store small and unchanging values in memory. Interning means that Python only stores one copy of an object in memory, even if multiple variables reference it. This saves memory and improves performance.
Integers are one of the types of objects that are interned in Python. This means that all integer objects from -5 to 256 are stored in the same memory location. This is why the integer object is the same in memory for the following code:
Python
a = 10 b = 10 print(a is b)
Output:
True
However, interning is not applied to all objects in Python. For example, lists and other more complex data types are not interned. This means that every time you create a new list, a new memory space is allocated for it, even if the list contains the same elements as an existing list.
It is important to note that interning can be disabled in Python. To do this, you can set the sys.intern variable to False. However, this is not recommended, as it can lead to performance problems.
Here are some additional benefits of interning:
It reduces the number of objects that need to be garbage collected.
It makes it easier to compare objects for equality.
It can improve the performance of operations that involve objects, such as hashing and object lookups.
Overall, interning is a powerful technique that Python uses to improve memory usage and performance.

How Do Lists Work In Python Programming Language?
Lists in Python are one of the most versatile and widely used data structures. A list is an ordered collection of items, which can be of any data type such as integers, strings, or even other lists. Lists are defined using square brackets [] and elements are separated by commas. For example, my_list = [1, "apple", 3.5, True] is a valid list containing different data types.
Lists are mutable, meaning you can change their content after creation. You can add elements using methods like .append() to add a single item or .extend() to add multiple items. Elements can be accessed using indexing, where the first element starts at index 0 (my_list[0]). Python also supports negative indexing, allowing access from the end of the list. You can remove items using .remove(), .pop(), or the del statement. Slicing allows you to extract parts of the list, such as my_list[1:3] to get a subsist.
Because of their flexibility, lists are commonly used in loops, conditionals, and functions to store and process collections of data.

Python includes basic arithmetic operators (+, -, *, /), as well as comparison operators (==, !=, >, <) and logical operators (and, or, not).
These operators help you perform calculations and build logic into your programs.
3. Control Structures
To make decisions and repeat actions, you’ll need:
if, elif, and else statements
for and while loops
Mastering control structures allows you to write dynamic programs that can handle a variety of tasks.
4. Functions
Functions are blocks of code designed to perform a specific task. They make your code more modular and reusable.
def greet(name):
print(f"Hello, {name}!")
5. File Handling
Python makes it easy to read from and write to files—an essential skill if you're working with data or saving information.
with open("data.txt", "r") as file:
content = file.read()
6. Error Handling
Learning to handle errors gracefully using try, except, and finally blocks is important for building reliable software.

Get Started Coding for non-programmers

How to Get Started with Coding: A Guide for Non-Techies
If you ever considered learning how to Get Started Coding for non-programmers but were intimidated by technical terms or daunted by the prospect, you're in good company. The good news is that coding isn't for "techies" alone. Anyone can learn to code, no matter their background or experience. In this guide, we'll take you through the fundamentals of how to get started coding, whether you're looking to create a website, work with data, or simply learn how the technology that surrounds you operates. Why Learn to Code? Before diving into the "how," it's worth knowing the "why." Coding can unlock new doors, both personally and professionally. Some of the reasons why learning to code is worth it include: Problem-solving abilities: Programming allows you to dissect difficult problems and identify solutions. Career adaptability: More and more careers, from marketing to medicine, are turning to coding as a requirement. Empowerment: Code knowledge enables you to have a better understanding of the technology you're using daily and enables you to own your own project development. Creativity: Coding isn't purely logical—it's also about making new things and creating your own ideas. Step 1: Choose Your Learning Path Before you start, consider what you are most interested in. The route you take will depend on what you want to do. These are some of the most popular routes: Web Development: Creating websites and web apps (learn HTML, CSS, JavaScript). Data Science: Examining data, visualizing patterns, and making informed decisions based on data (learn Python, R, or SQL). App Development: Creating mobile apps for iOS or Android (learn Swift or Kotlin). Game Development: Building video games (learn Unity or Unreal Engine using C# or C++). Take a moment to determine which area speaks to you. Don't stress about choosing the "perfect" path—coding skills are interchangeable, and you can always make a change later. Step 2: Begin with the Basics After you've decided on your route, it's time to begin learning. As a novice, you'll want to begin with the fundamentals of coding. Here are some fundamental concepts to familiarize yourself with: Variables: A means of storing data (such as numbers or text). Data Types: Familiarity with various types of data, including integers, strings (text), and booleans (true/false). Loops: Doing things over and over again without writing the same code over and over. Conditionals: Deciding things in code using if-else statements. Functions: These are the Building blocks of code that can be reused to accomplish particular tasks. For instance, when you're learning Python, you could begin with a basic program such as: Step 3: Select the Proper Learning Material There's plenty of learning material out there for beginners, and the correct resource can mean a big difference in how rapidly you learn to code. Some of the most popular methods include: Online Courses: Websites such as Coursera, Udemy, edX, and freeCodeCamp provide sequential courses, and some of these are available free of charge.
