🐍 Python Code Introduction

📌 What is Python Code?

Python code is a set of instructions written in the Python programming language that tells the computer what to do. It is known for its clean, readable, and beginner-friendly syntax.

✨ Key Features of Python Code

Feature	Description
Simple Syntax	Easy to write and understand. Looks like plain English.
Indentation-based	Uses indentation (spaces) to define blocks instead of curly braces `{}`.
Dynamically Typed	No need to declare data types. Python detects it automatically.
Interpreted Language	Code runs line by line, making it easy to debug and test.
Extensive Libraries	Thousands of built-in and third-party modules for data, web, AI, and more.

🧪 Basic Python Code Example

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

Explanation:

# is used for comments.
print() is a built-in function to show output on the screen.
Text inside quotes is called a string.

🔁 Simple Program

name = input("Enter your name: ")
print("Welcome,", name)

Sample Output:

Enter your name: Sairam
Welcome, Sairam

🧱 Python Code Structure

Part	Example	Purpose
Variable	`x = 10`	Stores data
Function	`def greet():`	Groups reusable code
Conditionals	`if x > 5:`	Makes decisions
Loops	`for i in range(5):`	Repeats code
Comments	`# This is a comment`	Describes the code (not executed)
