问题

以下是翻译好的代码部分：

  1. def add(num1, num2):
  2.     ans = num1 + num2
  3.     print(ans)
  5. def subtract(num1, num2):
  6.     ans = num1 - num2 
  7.     print(ans)
  9. def multiply(num1, num2):
  10.     ans = num1 * num2
  11.     print(ans)
  13. def divide (num1, num2):
  14.     if num2 == 0:
  15.         print("嘿，你不能这样做")
  16.     else:
  17.         ans = num1 / num2
  18.     print(ans)
  21. while True:
  22.     option = input("你想做什么？加法（1），减法（2），乘法（3），除法（4）。选择相应的数字作为你的选项。")
  23.     if option == "1":
  24.         num1 = int(input("第一个数字是多少？"))
  25.         num2 = int(input("第二个数字是多少？"))
  26.         add(num1, num2)
  27.       
  28.     elif option == "2": 
  29.         num1 = int(input("第一个数字是多少？"))
  30.         num2 = int(input("第二个数字是多少？"))
  31.         subtract(num1, num2)
  32.         
  33.     elif option == "3":
  34.         num1 = int(input("第一个数字是多少？"))
  35.         num2 = int(input("第二个数字是多少？"))
  36.         multiply(num1, num2)
  38.     elif option == "4":
  39.         num1 = int(input("第一个数字是多少？"))
  40.         num2 = int(input("第二个数字是多少？"))

关于在VS Code中无法正常工作的问题，我无法提供具体的解决方案，因为我无法直接查看你的代码和环境设置。但是，你可以尝试以下几个步骤来解决问题：

  1. 确保你的VS Code已正确配置Python环境，并且已安装所需的依赖项。
  2. 检查代码中是否存在任何语法错误或拼写错误。
  3. 确保你的VS Code中的Python解释器与Replit中使用的解释器版本相同。
  4. 检查VS Code的输出窗口或终端窗口，查看是否有任何错误消息或警告。
  5. 尝试在VS Code中创建一个新的Python项目，并将代码复制到新项目中，然后再次运行。

如果问题仍然存在，你可能需要进一步调查和调试，或者寻求其他开发者的帮助。

  43.         divide(num1, num2)
  45.     print("Error, option not valid.")
  46.     print()

I ran this in Replit and it worked fine but for VS Code it is not working. What is the issue here?

在你的第三个选项中，即乘法选项，你忘记在输入之前写上 "int"。

这是修正方法：

  1. elif option == "3":
  2.     num1 = int(input("第一个数字是多少？"))
  3.     num2 = int(input("第二个数字是多少？"))
  4.     multiply(num1, num2)

我还建议只在用户输入的数字不在列表中时显示 "选项无效" 的文本。例如：

  1. def add(num1, num2): 
  2.     ans = num1 + num2 
  3.     print(ans)
  5. def subtract(num1, num2): 
  6.     ans = num1 - num2 
  7.     print(ans)
  9. def multiply(num1, num2): 
  10.     ans = num1 * num2 
  11.     print(ans)
  13. def divide (num1, num2): 
  14.     if num2 == 0: 
  15.         print("嘿，你不能这样做") 
  16.     else: 
  17.         ans = num1 / num2 
  18.         print(ans)
  20. while True: 
  22.     option = input("你想做什么？加法（1），减法（2），乘法（3），除法（4）。选择相应的数字作为你的选项。") 
  23.     if option == "1": 
  24.         num1 = int(input("第一个数字是多少？")) 
  25.         num2 = int(input("第二个数字是多少？")) 
  26.         add(num1, num2)
  28.     elif option == "2": 
  29.         num1 = int(input("第一个数字是多少？"))
  30.         num2 = int(input("第二个数字是多少？"))
  31.         subtract(num1, num2)
  33.     elif option == "3":
  34.         num1 = int(input("第一个数字是多少？"))
  35.         num2 = int(input("第二个数字是多少？"))
  36.         multiply(num1, num2)
  38.     elif option == "4":
  39.         num1 = int(input("第一个数字是多少？"))
  40.         num2 = int(input("第二个数字是多少？"))
  41.         divide(num1, num2)
  43.     else:
  44.         print("错误，选项无效。\n")
英文:

It seems like in your third option, the one for multiplication, you forgot to write "int" before your input.

Here's the fix:

  1. elif option == "3":
  2.     num1 = int(input("What is the first number? "))
  3.     num2 = int(input("What is the second number? "))
  4.     multiply(num1, num2)

I would also recommend having the "option not valid" text displayed only when the user inputs a number not listed. For example:

  1. def add(num1, num2): 
  2.     ans = num1 + num2 
  3.     print(ans)
  5. def subtract(num1, num2): 
  6.     ans = num1 - num2 
  7.     print(ans)
  9. def multiply(num1, num2): 
  10.     ans = num1 * num2 
  11.     print(ans)
  13. def divide (num1, num2): 
  14.     if num2 == 0: 
  15.         print("Hey, you can't do that man") 
  16.     else: 
  17.         ans = num1 / num2 
  18.         print(ans)
  20. while True: 
  22.     option = input("What would you like to do? Add (1), Subtract (2), Multiply (3), Divide (4). Choose the corresponding number for your option. ") 
  23.     if option == "1": 
  24.         num1 = int(input("What is the first number? ")) 
  25.         num2 = int(input("What is the second number? ")) 
  26.         add(num1, num2)
  28.     elif option == "2": 
  29.         num1 = int(input("What is the first number? "))
  30.         num2 = int(input("What is the second number? "))
  31.         subtract(num1, num2)
  33.     elif option == "3":
  34.         num1 = int(input("What is the first number? "))
  35.         num2 = int(input("What is the second number? "))
  36.         multiply(num1, num2)
  38.     elif option == "4":
  39.         num1 = int(input("What is the first number? "))
  40.         num2 = int(input("What is the second number? "))
  41.         divide(num1, num2)
  43.     else:
  44.         print("Error, option not valid.\n")

除了在选项3周围加上int()包装器之外，我建议将错误消息移动到循环内部，以避免重复打印。否则，在VS Code中它可以正常工作。

  1.  elif option == "4":
  2.      num1 = int(input("第一个数字是多少？"))
  3.      num2 = int(input("第二个数字是多少？"))
  4.      divide(num1, num2)
  6.  else:
  7.      print("错误，选项无效。")
  8.  print()
英文:

In addition to putting int() wrappers around option 3 I would suggest to move the error message inside the loop to avoid repeated printing.Otherwise, it works fine in VS Code.

  1.  elif option == "4":
  2.      num1 = int(input("What is the first number? "))
  3.      num2 = int(input("What is the second number? "))
  4.      divide(num1, num2)
  6.  else:
  7.      print("Error, option not valid.")
  8.  print()
