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 combinationscards = ['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 combinationscards = ['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')] ```
