Mastering the Basics: How Python Functions Work (with Code)
# This program demonstrates how to define and call a function in Python, including passing arguments and returning a value. def calculate_rectangle_area (width, height): # Defines a function named 'calculate_rectangle_area' that accepts two parameters. area = width * height # Multiplies width by height and stores the result in 'area'. return area # Sends the calculated area value back to the caller. # Main program execution starts here room_width = 12 # Assigns the integer value 12 to 'room_width'. room_height = 15 # Assigns the integer value 15 to 'room_height'. # Calls the function and stores the returned result in 'total_area'. total_area = calculate_rectangle_area(room_width, room_height) print ( "The area of the room is:" , total_area) # Prints the final message and result to the console.
