组合
combinations：不考虑顺序的排列组合 import itertools print list(itertools.combinations([1,2,3,4],3)) [(1, 2, 3), (1, 2, 4), (1, 3, 4), (2, 3, 4)] permutations：考虑顺序的排列组合 import itertools print list(itertools.permutations([1,2,3,4],2)) #第二个参数2表示要选几个对象 [(1, 2), (1, 3), (1, 4), (2, 1), (2, 3), (2, 4), (3, 1), (3, 2), (3, 4), (4, 1), (4, 2), (4, 3)]
