事实上，您通常不必检查布尔值的相等或不相等。您只需将变量作为 if 或 elif 的条件，Python 就会理解您的意思。

By putting the parenthesis after True and False, you're signalling to the interpreter that you're trying to call them like a function. Just remove the parenthesis, and you should be good to go.
In fact, you usually don't have to check equality or inequality for Boolean values. You can just put the variable as the condition to the if or elif and Python will understand what you meant.

通过在
True和False之后放置括号，您可以向解释器发出信号，表明您正在尝试像函数一样调用它们。只需删除括号，您就可以开始了。事实上，您通常不必检查布尔值的相等或不相等。您只需将变量作为
if或elif的条件，Python 就会理解您的意思。By putting the parenthesis after
