我正在制作计算器，问题出在第 42 行 TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'int'

Question

无法弄清楚第 42 行不断收到错误 TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'int' 有人可以建议我如何修复它，因为我已经坚持了几个小时代码是如何工作的你运行它然后你选择你想要在这种情况下做哪种类型的计算圆圈被打破并且由于某种原因它不会工作它应该如何工作是def check检查字符串是否是数字或字母，如果它们是数字，它会继续，如果是字母，它会重新开始，并说你需要选择数字而不是字母

Answer 1

    num = str(input("What number would you like to find out the power off: "))
    power = str(input("what power do you to do: "))
    check(num, power)
    answer = int(num**power)

您打算将“num”转换为 int，然后取幂，但您没有对齐括号。
