在 while 循环中，您如何保存数据以便在循环结束时将 output 输入所有数据，而不仅仅是在下一个 while 循环中重置

Question

bottles = [] 

while True:

    option = str(input('which option would you like?'))
    howmany = int(input('how many would you like?'))
    tax = float(.06)
    

    if option == '1':
      bottles = [int(howmany) for _ in range(howmany)]
     # Multiply each value in bottle by 0.1 & print the sum
      total = (sum([(b*.99) for b in bottles]))
      print((total*tax)+total)
    
    elif option == '2':
      bottles = [int(howmany) for _ in range(howmany)]
     # Multiply each value in bottle by 0.1 & print the sum
      total = (sum([(b*.79) for b in bottles]))
      print((total*tax)+total)

    elif option == '3':
      bottles = [int(howmany) for _ in range(howmany)]
     # Multiply each value in bottle by 0.1 & print the sum
      total = (sum([(b*1.09) for b in bottles]))
      print((total*tax)+total)

我正在努力做到这一点，所以这个命令就像一群人点餐一样。 如果该组中有两个人，它将接收这两个输入并将它们一起打印。 指定组中有多少人就是循环运行的次数。 希望这是有道理的

＃代码

 quitoption = str(input('would you like to contiune? yes or quit '))

    if quitoption == 'quit':
        print('thank you we will have your order right up')
        quit()

    else: print("contiune")

Answer 1

这就是你想要做的：

bottles = [] 
tax = float(.06)
total = 0

while True:
    option = input('which option would you like? ')
    if option == '0':
        break

    howmany = int(input('how many would you like? '))
    option = int(option)
    bottles.extend( [option] * howmany )
    
    if option == 1:
        total += howmany * .99
    
    elif option == 2:
        total += howmany * .79

    elif option == 3:
        total += howmany * 1.09

print( "You ordered these bottles:", bottles )
print( "Total before tax:", total )
print( "Total after tax:", total * (1+tax))

Output：

which option would you like? 1
how many would you like? 5
which option would you like? 2
how many would you like? 3
which option would you like? 3
how many would you like? 2
which option would you like? 0
You ordered these bottles: [1, 1, 1, 1, 1, 2, 2, 2, 3, 3]
Total before tax: 9.5
Total after tax: 10.07

Answer 2

如果我正确地解决了你的问题，而你的问题是当 while 循环结束时工作列表bottles不是你希望的
那么这可能是因为你每次 while 循环迭代重写变量bottle 3次而不是向它添加任何东西
所以而不是这个bottles = [int(howmany) for _ in range(howmany)]你会尝试这样的东西for _ in range(howmany): bottles.append(int(howmany))
