如何使用多个条件过滤Python列表？

Question

我有这个列表理解，如果它们不在列表lst_fcflds中，则返回列表RROPFields中的元素：

nfld_rrop = [i for i in lst_fcflds if i not in RROPFields]

并想要一个过滤器，这样如果OBJECTID或SHAPE在lst_fclfds中，它们也不会被返回 - 例如：

nfld_rrop = [i for i in lst_fcflds if i not in RROPFields and not in ["OBJECTID","SHAPE"]]

Answer 1

你只是缺少一个i

nfld_rrop = [i for i in lst_fcflds if i not in RROPFields and i not in ["OBJECTID","SHAPE"]]
                                                              ^

但是为了提高性能，我会首先添加一步来创建set，以便您可以更快地进行成员资格查找。

filters = set(RROPFields + ["OBJECTID", "SHAPE"])
nfld_rrop = [i for i in lst_fcflds if i not in filters]
