🔤 Variables in Python

A variable is like a container that stores data. You don’t need to define the data type.

x = 5  
name = "John"  
price = 99.99

🔁 Loops in Python

Use for or while loops to repeat actions.

for i in range(3):  
    print("Hello")

🧮 Functions in Python

Functions help reuse code blocks with input/output.

def greet(name):  
    return "Hello " + name  
print(greet("Alice"))
