我正在尝试创建一个基本计算器，使用定义的“globalinputnum”来根据它在输入中接收的操作来请求输入。但似乎我无法使其发挥作用：（

在你的代码中：

#Code
while repeat_option in repeat:
choice = input("Input type of operation!(+,-,*,/,^2,^1/2)")
globalinputnum
if choice in addition:
    print(num1,"+",num2,"=",(num1+num2))

如果您需要在名称后面加上parens，那么您实际上并未调用globalinputnum。

#Code
while repeat_option in repeat:
choice = input("Input type of operation!(+,-,*,/,^2,^1/2)")
globalinputnum()
if choice in addition:
    print(num1,"+",num2,"=",(num1+num2))

有没有办法让这项工作成功？
