Is there an easy way to find all the subset with a specific length of a list, using Python?

Question

If I have a list, say

a=[1,2,3,4]

I want to specify a length, let's say 3, then I can find all the subsets:

[[1,2,3],
[1,2,4],
[2,3,4]]

Does Python has a function so that I can do this quickly?

you can try **list(itertools.combinations(a, 3))** – Arun Sg Jun 02 '21 at 15:14 — Arun Sg, Jun 02 '21 at 15:14

You can do this:

import itertools
print(list(itertools.combinations(your_set, length_of_subsets)))
