expand_more We can use combinations within the itertools module to get all the possible combinations of elements in a sequence in Python.
To get all the possible pair combinations from my_list:
from itertools import combinations
cards = ['Ace', 'King', 'Queen', 'Jack']pair_obj = combinations(cards, 2)
pairs = [*pair_obj] #unpacking into a listprint(pairs)
[('Ace', 'King'), ('Ace', 'Queen'), ('Ace', 'Jack'), ('King', 'Queen'), ('King', 'Jack'), ('Queen', 'Jack')]
In the above example we generated combinations of 2, however, this can be specified accordingly:
itertools.combinations(iterable, r)
To generate combinations of 3 from my_list:
from itertools import combinations
cards = ['Ace', 'King', 'Queen', 'Jack']pair_obj = combinations(cards, 3)
pairs = [*pair_obj] #unpacking into a listprint(pairs)
[('Ace', 'King', 'Queen'), ('Ace', 'King', 'Jack'), ('Ace', 'Queen', 'Jack'), ('King', 'Queen', 'Jack')]
