Learn the fundamentals of Python programming.

Introduction to Python

Python is a versatile and popular programming language known for its simplicity and readability. It's widely used in various domains, including web development, data science, and automation.

Getting Started

If you're new to Python, start by installing Python on your computer. You can download it from the official Python website.

Hello World in Python

Let's begin with a classic example, the "Hello, World!" program in Python:

print("Hello, World!")

Variables and Data Types

Python supports various data types, including integers, floats, strings, lists, and more. You can declare variables like this:

name = "Alice"
age = 30

Variables and Data Types

Python supports various data types, including integers, floats, strings, lists, and more. You can declare variables like this:

name = "Alice"
age = 30
salary = 50000.5
is_student = False
fruits = ["apple", "banana", "cherry"]

Conditional Statements

Conditional statements allow you to make decisions in your code. Here's an example using an if statement:

if age >= 18:
    print("You are an adult.")
else:
    print("You are a minor.")

Loops

Loops let you repeat actions. The for loop is handy for iterating over lists:

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)

Functions

Functions are reusable blocks of code. Here's a simple function to add two numbers:

def add(a, b):
    return a + b

result = add(3, 5)
print("Result:", result)
