我收到AttributeError: 'NoneType' object has no attribute 'rstrip'

所以我添加了if clist is not None: 但我一直收到同样的错误。为什么？

if clist is not None:
    result = [
        [name, clist.rstrip()] 
        for name, clist in zip(
            fragments[::group_count+1],
            fragments[group_count::group_count+1]
        )
    ]

AttributeError: 'NoneType' object has no attribute 'rstrip'

【问题讨论】：

不是clist。片段的元素之一必须是无。

【解决方案1】：

试试这个。

Clist out of the list comprehension is not None But some of the values inside fragment in None,这就是你得到这个错误的原因。

您需要像下面一样添加if clist is not None inside list comprehension。

result = [[name, clist.rstrip()] for name, clist in zip(
            fragments[::group_count+1],
            fragments[group_count::group_count+1]
        ) if clist is not None]

如果您有任何其他错误，请在评论中告诉我。

【解决方案2】：

最后调用的模块：npc_invite_situation_drama_node.py 上次调用的函数：_get_zone_id 错误信息：（AttributeError: 'NoneType' object has no attribute 'vacation_or_home_zone_id'），CategoryID: npc_invite_situation_drama_node:230
