Python calculating surface area of walls, HELP! What is wrong with my code? watch

    • Thread Starter

    *What is wrong with my code? It only calculates the surface area for one of the walls and not the others, what am I doing wrong!? Please help ASAP
    print("Welcome to the estimation menu!")
    global total
    global NumberOfRooms
    global NumberOfWalls
    global SurfaceArea

    CustomerNumber = input("What is your customer number?: ")
    DateOfEstimation = input("What is your date of estimation?: ")

    def estimation():
    NumberOfRooms = 0
    counter = 0
    total = 0
    NumberOfWalls = 0
    SurfaceArea = 0
    height = 0
    width = 0
    TotalHeightOfWalls = 0
    TotalWidthOfWalls = 0

    NumberOfRooms = int(input("How many rooms would you like painted?: "))
    counter = int(NumberOfRooms) + int(counter)
    while int(counter)>0:
    name = input("What is the name of the room you would like painted? For example, dining, lounge, bedroom etc. : ")
    wallpaper_removed = input("Do you want the wall paper to be removed? Type 'Yes' or 'No': ")
    if wallpaper_removed == "Yes":
    total = int(total) + 70
    numberofwalls = int(input("Please enter the number of walls you would like painted for this room: "))
    while int(numberofwalls) > 0:
    height = int(input("What is the height of the wall? (In Meters): "))
    width = int(input("What is the width of the wall? (In Meters): "))
    numberofwalls = int(numberofwalls) - 1
    counter = int(counter)-1
    TotalHeightOfWalls = int(TotalHeightOfWalls + height)
    TotalWidthOfWalls = int(TotalWidthOfWalls + width)
    SufaceArea = (TotalWidthOfWalls * TotalHeightOfWalls)
    print("Total Surface Area of walls =",SufaceArea)
    #You just need to ask for the height and width, then add it to the total

    What do you mean?

    You could try using the 'else / elseif' function :dontknow:

    It might also be due to the fact that you haven't integrated 'global total' in the second line at the end.
Do you agree with the PM's proposal to cut tuition fees for some courses?
