【问题描述】:
list1 = [[['a','b'],['c','d']],[['f','g'],['h','i']],[['j','k','l'], ['a','b']]]
list2 = [['a','b'],['c','d'],['f','g'],['h','i']]
所以在 list1 中,有 3 个列表。我想检查 list1 中的列表是否是列表 2 的子集。但是列表列表中的所有列表都必须在 list2 中才能获得 True/Correct。如果所有内容都在 list2 中,则为 true,如果不是每个列表,则为 false。
[['a','b'],['c','d']]
[['f','g'],['h','i']]
[['j','k','l'], ['a','b']]
所以条件如下
These are from list1, and we're checking against list2
Both [a, b] and [c, d] should be in list 2 -> Both are in list 2, so Return True
Both [f, g] and [h, i] should be in list 1 -> Both are in list 2, so return true
Both [j, k, l] and [a, b] should be in list 1 -> f, k, l is not in list 2, so return False even though a, b are in list 2
Here is my desired output for above results
[True, True, False]
或
val1 = True
val2 = True
val3 = False
代码
def xlist(list1, list2):
if all(letter in list1 for letter in list2):
print('True')
print xlist(list1, list2)
final = []
"""I am checking i in list1. In actual, I should be checking all lists within the list of list1."""
for i in list1:
print(xlist(list1, list2))
final.append(xlist(list1, list2))
print(final)

虽然很明显,但您并没有说明实际出了什么问题。如果您遇到错误,您应该附上它。如果您的输出错误,您应该向我们展示实际输出与预期输出的对比(您实际上是这样做的,只是缺少实际输出)
