问题

这个程序允许用户输入货币并选择一个商品以输出价格。

在程序的末尾，if语句中的部分，例如 if purchase_choice == 1: print("************ The item costs $1.00 ************") 以及之后的语句，在输出中没有打印。有人可以帮助我吗？

以下是代码的翻译部分：

  1. print("*********************************")
  2. print("欢迎来到自动贩卖机Bravo！")
  3. print("*********************************")
  4. print("如果您想要选择商品，请将适当的货币投入机器中。")
  6. # 货币充值
  7. num_5Dollars = 5.00
  8. num_Dollars = 1.00
  9. num_Quarters = 0.25
  10. num_Dimes = 0.10
  11. num_Nickels = 0.05
  12. num_Pennies = 0.01
  14. print()
  15. print("请投入：")
  16. if num_5Dollars == 5.00:
  17.     print("5.00美元钞票")
  18. if num_Dollars == 1.00:
  19.     print("1.00美元钞票")
  20. if num_Quarters == 0.25:
  21.     print("0.25美元的硬币")
  22. if num_Dimes == 0.10:
  23.     print("0.10美元的硬币")
  24. if num_Nickels == 0.05:
  25.     print("0.05美元的硬币")
  26. if num_Pennies == 0.01:
  27.     print("0.01美元的硬币")
  29. user_val = float(input())
  31. if int(user_val) == 0:
  32.     print("输入0以取消")
  34. print("任何时候，如果您想取消操作或返回上一个菜单，请输入0。谢谢！:")
  35. print()
  36. print(int(user_val))
  37. print()
  38. print("************ 机器中的总金额是：", user_val, " ************")

  79.         print("************ 商品价格为 $1.99 ************")
英文:

The program allows the user to enter money and select an item that outputs the price.

Towards the end, the if statements, if purchase_choice == 1: print("************ The item costs $1.00 ************") and the following statements after that one, is not printing in the output. Can someone help me?

Here's the code.

  1. print("*********************************")
  2. print("Welcome to Vending Machine Bravo!")
  3. print("*********************************")
  4. print("If you would like to make a selection, please insert the appropriate currency into the machine.")

你需要将用户输入的字符串转换为整数。

purchase_choice = int(input())

英文:

You need to convert the user input string to an integer.

purchase_choice = int(input())
