python - 迭代对象属性并更改它们？

Question

有没有办法做我想在这里做的事情:

for item in [self.docket_numbers, self.neutral_citations,
             self.lower_courts, self.lower_court_judges,
             self.dispositions, self.judges, self.nature_of_suit]:
    if item is not None:
        item = [clean_string(sub_item) for sub_item in item]

显然，在最后一行，我需要将列表解释的结果分配回对象...但我不确定如何。

Answer 1

遍历名称；然后你可以使用 getattr 和 setattr。

for attr in ('docket_numbers', 'neutral_citations',
             'lower_courts', 'lower_court_judges',
             'dispositions', 'judges', 'nature_of_suit'):
    item = getattr(self, attr)
    if item is not None:
        setattr(self, attr, [clean_string(sub_item) for sub_item in item])
