python - 如何修复无效语法

Question

在标题为 #Title type and size 的部分中，我想打印出每个图 block 的定价，但我无法将数字相除。我该如何解决这个问题？谢谢

print("Welcome to Terry Cotta's Tiling Company!")

#Dimenstion of area to be tiled
areaLength = int(input('Input length of area to be tiled in metres: '))
if areaLength <= 0:
    print('Area cannot be lower than 0')
    areaLength = int(input('Input length of area to be tiled in metres: '))
areaWidth = int(input('Input width of area to be tiled: '))
if areaWidth <= 0:
    print('Area cannot be lower than 0')
    areaWidth = int(input('Input length of area to be tiled in metres: '))
areaArea = areaLength*areaWidth

#Tile type and size
tiles = {'ceramic': '3', 'granite': '5', 'marble': '10'}

for x in tiles:
    print(x.title() + " -  Small: $" + int(tiles[x])/2 + "  Medium: $" + tiles[x] + "  Large: $" + int(tiles[x])*(2)

tileType = input("What type of tile would you like? Ceramic, granite or marble?: ")
tileType = tileType.lower()
while tileSuitable != 'yes':
    if tileType not in tiles:
        print('We do not provide that type of tile. Please enter again.')
        tileType = input("What type of tile would you like? Ceramic, granite or marble?: ")
if tileType in tiles:
    tileSize = input('What size tile would you like? Small, medium or large: ') 

#        else:
#            print(tileType.title() + ' costs $' + tiles[tileType])
#            confirmTileType = input('Is this your desired material? ')
#            confirmTileType = confirmTileType.lower()
#            if confirmTileType == 'no':
#                tileType = input("What type of tile would you like? Ceramic, granite or marble. Type 'cost' for cost of materials: ")

Answer 1

这是因为你没有关闭打印功能

是:

print(x.title() + " -  Small: $" + int(tiles[x])/2 + "  Medium: $" + tiles[x] + "  Large: $" + int(tiles[x])*(2)

应该是:

print(x.title() + " -  Small: $" + int(tiles[x])/2 + "  Medium: $" + tiles[x] + "  Large: $" + int(tiles[x])*(2))

对代码进行小更改:

print("Welcome to Terry Cotta's Tiling Company!")
areaLength = int(input('Input length of area to be tiled in metres: '))


#You could loop until you get correct value


while areaLength <= 0:
    print('Area cannot be lower than 0')
    areaLength = int(input('Input length of area to be tiled in metres: '))
areaWidth = int(input('Input width of area to be tiled: '))

#Same here loop until you get the correct value 


while areaWidth <= 0:
    print('Area cannot be lower than 0')
    areaWidth = int(input('Input length of area to be tiled in metres: '))
areaArea = areaLength*areaWidth

tiles = {'ceramic': '3', 'granite': '5', 'marble': '10'}

for x in tiles:
    print(x.title() + " -  Small: $" + str(int(tiles[x])/2) + "  Medium: $" + tiles[x] + "  Large: $" + str(int(tiles[x])*(2)))

tileType = input("What type of tile would you like? Ceramic, granite or marble?: ")
tileType = tileType.lower()


#You had undeclared variable here so changed it


#And I really don't know what you were trying to do here 


while tileType != 'yes':
    if tileType not in tiles:
        print('We do not provide that type of tile. Please enter again.')
    tileType = input("What type of tile would you like? Ceramic, granite or marble?: ")
if tileType in tiles:
    tileSize = input('What size tile would you like? Small, medium or large: ')
