find all possible pairs of size k in array using library in python code example

Example 1: how to get all possible combinations in python

all_combinations = [list(zip(each_permutation, list2)) for each_permutation in itertools.permutations(list1, len(list2))]

Example 2: python create a program that runs through all possible combinations

from itertools import combinations

lst = ["a" ,"b", "c"]
lengthOfStrings = 3
for i in combinations(lst, lengthOfStrings):
  print(i)
