Question

如果用户输入了＆＃39; N＆＃39;不，你怎么避免50美元的额外费用，并跳过要求高度和宽度来计算表面积，并继续其余的代码？请记住，我没有在代码之后写下问题;如果用户键入了＆＃39; Y＆＃39;如果是，那么将添加50美元，程序将询问房间内每面墙的宽度和高度。

total_surface_area = 0
number = int(input("Number of rooms to paint")
print("\n***ROOM DETAILS***")
for room in range(number):
    room_name = input("\n\nPlease enter the name of the room:")
    wall_number = int(input("Number of walls in the room:"))
    wallpaper = input("\nWould you like to remove the paint? (Y for Yes/N for No). If yes, $50 will be charged per room:")

Answer 1

对于我们来说，确定问题的最佳解决方案是什么，我可能有点过于模糊，但我怀疑您正在寻找continue和break语句。您可以找到解释here。

这可以说明如何使用这两种语句：

total_surface_area = 0
# You were missing a parenthesis in the following line.
number = int(input("Number of rooms to paint"))
print("\n***ROOM DETAILS***")
for room in range(number):
    print('=== details of room number '+str(room)+' ===')
    room_name = input("\n\nPlease enter the name of the room:")
    wall_number = int(input("Number of walls in the room:"))

    print("\nWould you like to remove the paint? (Y for Yes/N for No). If yes, $50 will be charged per room:")
    while True:
        buffer = input()
        if buffer == 'Y':
            wallpaper = True
            break
        elif buffer == 'N':
            wallpaper = False
            break
        else:
            print('please anser "Y" or "N"')

    if wallpaper:
        print('I will now ask many more questions.......')
        # continue asking questions ...
    else:
        # move to the next room
        continue

这可能就是你要找的东西：

from distutils.util import strtobool
total_surface_area = 0
extra_cost = 0
number = int(input("Number of rooms to paint")
print("\n***ROOM DETAILS***")
for room in range(number):
    room_name = input("\n\nPlease enter the name of the room:")
    wall_number = int(input("Number of walls in the room:"))
    wallpaper = input("\nWould you like to remove the paint? (Y for Yes/N for No). If yes, $50 will be charged per room:")
    if strtobool(wallpaper):
        extra_cost += 50
        dimensions = []
        for wall in range(wall_number):
            dimensions.append(input("Please input wall dimensions..."))

    ...

编码问题的条件逻辑？
