Bool对象不支持项目分配

Question

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

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

我得到一个奇怪的错误，其中python告诉我bool对象不支持项目分配，我不知道为什么。

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

Answer 1

代码中的 else ，你直接将一个布尔值分配给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
