Create unique cartesian product from a list

Question

How do I create a cartesian product of a list itself with unique elements?

For example, lists = ['a', 'b', 'c'], and I want to create [['a', 'b'], ['a','c'], ['b','c']].

That isn't a Cartesian product -- it is a set of combinations. Just use `itertools.combinations(lists,2)` — John Coleman, Feb 04 '21 at 01:24

from itertools import combinations
lists = ['a', 'b', 'c']
print(list(map(list, combinations(lists,2))))
