我在第52行得到错误

Unsupported operand type for -= str and int

Answer 1

您为gold2提供了一个字符串值：

gold2 = str(500)

但尝试减去整数：

gold2 -= taX

不要这样做：

>>> gold2 = str(500)
>>> gold2 -= 30
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -=: 'str' and 'int'

也许你的意思是让gold2成为整数？

为什么我会收到此错误“不支持的操作数类型”？
