Write a python function to generate a random combination from user provided list and user specified length.

Solution

import itertools
def get_random_combination(input_list, combination_length):
    if(len(input_list) < combination_length):
        print("Requested combination length less than length of list")
        return
    combination_list = list(itertools.combinations(input_list, combination_length))
    return random.sample(combination_list, 1)
