比较python中的两个列表，其中元素的顺序不同

Question

I have multiple lists eg

list1=[1,4,5]
list2=[4,1,5]
list3=[1,5,4]

two lists are considered same if they have the same elements. Also the lists can be nested lists

list1=[[1,4],5,4]
list2=[5,4,[1,4]]

How do i compare them?

Answer 1

You can flatten your lists then use set to keep the unique elements then compare :

>>> from compiler.ast import flatten
>>> list1=[[1,4],5,4]
>>> list2=[5,4,[1,4]]
>>> set(flatten(list1))==set(flatten(list2))
True
