Introduction to Python

Python is a versatile, high-level programming language known for its simplicity and readability. Created by Guido van Rossum in 1991, it has since become one of the most popular languages in the world.

Key Features of Python

• Easy to learn and read
• Interpreted language
• Dynamically typed
• Object-oriented
• Extensive standard library
• Cross-platform compatibility

Why Choose Python?

Python's simplicity and versatility make it an excellent choice for beginners and experienced programmers alike. It's widely used in various fields, including:

• Web development
• Data science and machine learning
• Artificial intelligence
• Scientific computing
• Automation and scripting

Getting Started with Python

To begin your Python journey, you'll need to install Python on your computer. Once installed, you can start writing and running Python code.

Your First Python Program

Let's write a simple "Hello, World!" program:

print("Hello, World!")
    

This code uses the print() function to display text on the screen. Python's syntax is straightforward, making it easy to understand and write code quickly.

Python Syntax Basics

Python uses indentation to define code blocks, unlike many other languages that use curly braces. This enforces clean, readable code. Here's a simple example demonstrating Python's syntax:

# This is a comment
if 5 > 2:
    print("Five is greater than two!")
    

In this example, we see:

• Comments start with a #
• Indentation is used to define the code block inside the if statement
• No semicolons are needed at the end of lines

Python Variables and Data Types

Python uses dynamic typing, which means you don't need to declare variable types explicitly. Here's an example:

x = 5           # integer
y = "Hello"     # string
z = 3.14        # float
