我需要帮助在python中创建一个显示所有可能组合的程序。例如:我给它编号"1 2 3"我给了我"1 3 2","3 2 1","3 1 2","2 1 3","2 3 1"。
使用
1 2 3 4 5 6 7 8 9 10 11 12 13 | import itertools perms = itertools.permutations([1,2,3]) for perm in perms: print perm >>>(1, 2, 3) >>>(1, 3, 2) >>>(2, 1, 3) >>>(2, 3, 1) >>>(3, 1, 2) >>>(3, 2, 1) |
1 2 3 4 5 6 7 | from itertools import combinations as c for x in c([1, 2, 3],2): print x (1, 2) (1, 3) (2, 3) print [x for x in c(range(5), 3)] [(0, 1, 2), (0, 1, 3), (0, 1, 4), (0, 2, 3), (0, 2, 4), (0, 3, 4), (1, 2, 3), (1, 2, 4), (1, 3, 4), (2, 3, 4)] |
