循环遇到麻烦并收集用户输入

嗨，我正在从事一个自助服务程序的作业。在收集用户输入时，我很难尝试合并一个时循环。我希望我的代码收集一笔钱（用户输入），并提示用户需要支付多少钱。一旦支付的金额超过了应付的金额，我想继续进行其余的代码。这是我到目前为止所拥有的，但是即使用户付款不足，循环也会在2个输入后停止。

elif paid < TotalCost:
  due = TotalCost - paid
  while due > 0:
    print("You need to pay $",round(due,2)," more.")
    morepaid=float(input("Enter the amount paid: $"))
    if morepaid>TotalCost:
      change= morepaid- TotalCost
      print("Change due: $",round(change,2))
      print(" ")
      print("Thank you for visiting McDonald's")
  
    elif due== 0:
      print("Change due: $0.00")
      print(" ")
      print("Thank you for visiting McDonald's")
    else:
      due -= morepaid

Hi I'm working on an assignment where I make a self-service program. I'm having trouble trying to incorporate a while loop while collecting user input. I want my code to collect an amount of money (entered by the user) and prompt the user on how much more they need to pay. Once the amount paid exceeds the amount due, I want to continue with the rest of my code. This is what I have so far but the loop stops after 2 inputs, even if the user has not paid enough.

elif paid < TotalCost:
  due = TotalCost - paid
  while due > 0:
    print("You need to pay quot;,round(due,2)," more.")
    morepaid=float(input("Enter the amount paid: quot;))
    if morepaid>TotalCost:
      change= morepaid- TotalCost
      print("Change due: quot;,round(change,2))
      print(" ")
      print("Thank you for visiting McDonald's")
  
    elif due== 0:
      print("Change due: $0.00")
      print(" ")
      print("Thank you for visiting McDonald's")
    else:
      due -= morepaid

您可以简单地从到期中减去金额，您不需要另一个变量totalpaid。

elif paid < totalCost:
    due = totalCost - paid:
    while due > 0:
        print("You need to pay $",round(due,2)," more.")
        morepaid=float(input("Enter the amount paid: $"))
        due -= morepaid

You can simply subtract the amount paid from due, you don't need another variable totalpaid.

elif paid < totalCost:
    due = totalCost - paid:
    while due > 0:
        print("You need to pay quot;,round(due,2)," more.")
        morepaid=float(input("Enter the amount paid: quot;))
        due -= morepaid
