Introduction to Python

Python is a high-level, interpreted programming language known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991. Python is widely used for web development, data analysis, artificial intelligence, and many other applications.

Basic Syntax and Structure

Python uses indentation to define blocks of code. Unlike other languages, Python does not use curly braces {} or keywords to denote the beginning and end of blocks. Instead, it relies on whitespace for its syntax.

# This is a comment
print("Hello, World!")

Variables and Data Types

In Python, variables are names used to store values. Python is dynamically typed, meaning you don't have to declare the data type of a variable explicitly.

age = 25
name = "Alice"
is_student = True

Control Flow

Python provides various control flow statements to control the execution of a program. These include if, else, for, and while statements.

if age >= 18:
    print("You are an adult.")
else:
    print("You are not an adult.")

Functions

Functions are reusable blocks of code that perform a specific task. They help in organizing and modularizing your code.

def greet(name):
    print(f"Hello, {name}!")

greet("Alice")
