Getting the subsets of a set in Python

Question

Suppose we need to write a function that gives the list of all the subsets of a set. The function and the doctest is given below. And we need to complete the whole definitio

Answer 1

If you want to get all subsets without using itertools or any other libraries you can do something like this.

def generate_subsets(elementList):
    """Generate all subsets of a set""" 
    combination_count = 2**len(elementList)

    for i in range(0, combination_count):   
        tmp_str = str(bin(i)).replace("0b", "")
        tmp_lst = [int(x) for x in tmp_str]

        while (len(tmp_lst) < len(elementList)):
            tmp_lst = [0] + tmp_lst

        subset = list(filter(lambda x : tmp_lst[elementList.index(x)] == 1, elementList))
        print(subset)
