* 순열 Permutations : 순서 다르면 다른 것으로 판단

from itertools import permutations

list(permutations([1, 2, 3, 4], 2))
# [(1, 2), (1, 3), (1, 4), (2, 1), (2, 3), (2, 4), (3, 1), (3, 2), (3, 4), (4, 1), (4, 2), (4, 3)]

* 조합 Combinations: 순서 신경 X

from itertools import combinations

print(list(combinations([1,2,3,4], 2)))
# [(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4)]

* Product

from itertools import product

print(list(product([1,2,3,4], repeat=2)))
# [(1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4), (4, 1), (4, 2), (4, 3), (4, 4)]

    l = s.split()[1:]

    for i in list(combinations(l, 6)): # 조합
        print(*i) # list 한 줄 출력
