Here are two examples of lists

list = [["mo", "thu"], ["we", "fri"], ["mo", "mo"]]
list2 = [["mo", "fri", "fri"], ["we", "we"]]

So these lists come in random order. I've given two examples here. What I want to do is compute all possible ways these lists can be permutated. On the level where it's list[1] * list[2] * list[3]. All possible combinations. A smaller example what I would like to reach is this:

list3 = [["we", "thu"],["fri", "thu"]]

--> 

[["we", "fri"], ["we", "thu"], ["thu", "fri"], ["thu", "thu"]]

Also, the lists are random so the amount of elements in the list or the nested lists can vary. I can python this out by alot of code but I was hoping there is an easier way to this.

Cheers

What you want is unclear but maybe what you want is the cartesian product of your list? If so, it is very simple:

list3 = [["we", "thu"],["fri", "thu"]]
import itertools
final_list = [list(v) for v in itertools.product(*list3)]
## [['we', 'fri'], ['we', 'thu'], ['thu', 'fri'], ['thu', 'thu']]
