How to Pair Elements from Short and Long Lists Using Permutations?

Matching Permutations: Aligning Long and Short Lists

Given two lists of different lengths, we aim to create pairings based on the length of the shorter list. Each element from the shorter list should correspond to a permutation of the elements from the longer list.

For instance, with names = ['a', 'b'] and numbers = [1, 2], we would obtain:

If the names list is longer, such as names = ['a', 'b', 'c'], the permutations would expand to include:

Solution Using itertools.product

A straightforward approach is to utilize the itertools.product function from the Python standard library. It generates a Cartesian product of input iterables, creating all possible combinations.

In our specific case, we can use itertools.product to pair the shorter list's elements with the permutations of the longer list. The permutations are generated by listing all possible reorderings of the longer list's elements.
