Creating Functions

Functions are reusable blocks of code that perform a specific task.

Syntax

def function_name(parameter1, parameter2):
    # code here
    return result

def greet(name):
    return f"Hello, {name}!"message = greet("Alice")
print(message)  # Hello, Alice!

Create a function called calculate_total that:

Takes two parameters: price and quantity

Returns the product (price × quantity)

Test it by calling the function with price=25 and quantity=4, then print the result.
