python - Bool对象不支持item赋值

Question

is_shooting = []
is_shooting.append(False)
ShootWeapon(0)    

def ShootWeapon(wep_num):
        is_shooting[wep_num] = True

我收到一个奇怪的错误，python 告诉我 bool 对象不支持项目分配，但我不确定为什么。

Traceback (most recent call last):

    main.InputEvents()

    is_shooting[wep_num] = True
TypeError: 'bool' object does not support item assignment

Answer 1

在代码中的其他地方，您直接将 bool 值分配给了 is_shooting 全局:

>>> is_shooting = [False]
>>> is_shooting[0] = True
>>> is_shooting = True
>>> is_shooting[0] = True
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'bool' object does not support item assignment

您必须搜索代码才能找到执行此操作的位置。
