This README provides an introduction to functions in Python - how to define, call, and use them effectively.
A function is a reusable block of code that performs a specific task.
def function_name(parameters):
# code block
return result
Example
def rectangle_area(width, height):
return area
width = int(input())
height = int(input())
area = width * height
rectangle_area(width, height)
print(area)
