repeat第一个列表，
permutate第二和
zip它一起
>>> from itertools import permutations, repeat>>> a = [1, 2, 3]>>> b = [4, 5, 6]>>> list(list(zip(r, p)) for (r, p) in zip(repeat(a), permutations(b)))[[(1, 4), (2, 5), (3, 6)], [(1, 4), (2, 6), (3, 5)], [(1, 5), (2, 4), (3, 6)], [(1, 5), (2, 6), (3, 4)], [(1, 6), (2, 4), (3, 5)], [(1, 6), (2, 5), (3, 4)]]
编辑 ：正如彼得·奥滕（Peter Otten）所指出的，内部
zip和
repeat都是多余的。
[list(zip(a, p)) for p in permutations(b)]
