python - typeError : isinstance() arg 2 must be a type or tuple of types >>>

>>> names=['jill','jack']
>>> isinstance(names,list)
Traceback (most recent call last):
  File "<pyshell#291>", line 1, in <module>
    isinstance(names,list)
TypeError: isinstance() arg 2 must be a type or tuple of types
>>>

我在这里想念什么吗？

最佳答案

您已通过分配给相同名称的本地变量来踩list。不要那样做
