Combinations using methods

 Combinations using methods:

    from itertools import combinations

    n=int(input())

    c=combinations([1,2,3,4],n)

    for i in list(c):

        print(i)

# with an element-to-itself combination 

    from itertools import combinations_with_replacement

    n=int(input())

    c=combinations_with_replacement([1,2,3],n)

    for i in list(c):

        print(i)
