如何在python中子集列表列表

您可以将它们转换为集合,然后检查它们的交点是否与必须设置的交点相同。

list_dummy = [['a', 'b', 'c'], ['d', 'b', 'c'], ['a', 'b', 'd'], ['d', 'a', 'c'] ]
must_have = ['a', 'b']
must_have_set = set(must_have)
print([x for x in list_dummy if set(x) & must_have_set == must_have_set])

您可以使用issubset

list_dummy = [['a', 'b', 'c'], ['d', 'b', 'c'], ['a', 'b', 'd'], ['d', 'a', 'c']]
must_have = ['a', 'b']
list_sub = [i for i in list_dummy if set(must_have).issubset(i)]
print(list_sub)
