list - 在元组内的列表中迭代成员

Question

想象一下有这个列表

[[1,2,3],[1,2,3],[1,2,3]]

如何获得这些排列：

[[1,2,3],[1,2,3],[1,2,3]]
[[1,2,3],[1,2,3],[1,3,2]]
[[1,2,3],[1,2,3],[2,1,3]]
[[1,2,3],[1,2,3],[2,3,1]]
....
[[1,2,3],[1,3,2],[1,2,3]]
[[1,2,3],[1,3,2],[1,3,2]]
[[1,2,3],[1,3,2],[2,1,3]]
....
[[3,2,1],[3,2,1],[3,2,1]]

Answer 1

import itertools
seq = [[1,2,3], [1,2,3], [1,2,3]]
for item in itertools.product(*[itertools.permutations(sublist) for sublist in seq]):
    print item

结果：
