Как мне написать код python, чтобы проверить, есть ли элементы, которые всегда встречаются вместе? Например, в приведенном выше примере 2,3 и 6,7 всегда встречаются в одних и тех же списках. (могут быть и другие, не уверены).
Это, конечно, не работает, но как я могу формально это кодировать или есть лучший подход к этому?
Ответ 8
Это скорее решение грубой силы, однако оно сгенерирует большой список всех элементов, которые происходят вместе, создавая перестановки каждого подписок в l
и фильтруя, чтобы найти любые перестановки, элементы которых все появляются в подписок l
. Если какие-либо перестановки передают это условие, перестановка будет добавлена к final_pairs
:
l = [[1,2,3],[6,5,4,3,7,2],[4,3,2,9],[6,7],[5,1,0],[6,3,2,7]]
import itertools
final_pairs = []
for i in l:
combos = [list(itertools.permutations(i, b)) for b in range(2, len(i))]
for combo in combos:
for b in combo:
if any(all(c in a for c in b) for a in l):
final_pairs.append(combo)
final_data = list(set(itertools.chain.from_iterable(final_pairs)))
Вывод:
