如何解決無效的語法

Question

在標題爲＃標題類型和大小的部分，我想打印出每個瓷磚的定價，但我不能劃分數字。我將如何解決這個問題？由於

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

那是因爲你沒有關閉print function

是：

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

應該是：

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

對您的代碼的小改動：

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: ')
