问题描述

我已经完成了Removing sublists from a list of lists,但是当我为我的数据集扩展它时,它不适用于我的情况。因此发布了一个新问题。

list1=[['A,C,D', 'Y', 'hello'],
['A,B,D', 'Y', 'hello'],
['B,C,D', 'Y', 'hello'],
['A,B,C,D', 'Y', 'hello'],
['A', 'Z', 'hello'],
['A,C', 'Z', 'hello'],
['B,C', 'Z', 'hello'],
['A,C', 'Z', 'hello'],
['A,B,C', 'Z', 'hello'],
['H,I,J,K', 'Z', 'hello'],
['H,K', 'Z', 'hello'],
['H,L', 'Z', 'hello'],
['I,J,K,L', 'Z', 'hello'],
['H,I,J,K,L', 'Z', 'hello'],
['B,C,D','Z','hi'],
['A,D,C,B','Z','hi']]

我想删除一些元素并在下面发布所需的输出:

**Output**
[['A,B,C,D', 'Y', 'hello'],
 ['A,B,C', 'Z', 'hello'],
 ['H,I,J,K,L', 'Z', 'hello'],
 ['A,D,C,B','Z','hi']]

我已尝试使用以下代码:

sets = [set(l) for l in lists]
new_list = [l for l,s in zip(lists, sets) if not any(s < other for other in sets)]

解决方案


您必须将子列表中的所有元素都拆分,,才能使用您已经找到的解决方案:

st = [{i for e in l for i in e.split(',') } for l in list1]
[l for l, s in zip(list1, st) if not any(s < other for other in st)]

输出:

[['A,B,C,D', 'Y', 'hello'],
 ['A,B,C', 'Z', 'hello'],
 ['H,I,J,K,L', 'Z', 'hello'],
 ['A,D,C,B', 'Z', 'hi']]
