各位大佬，这个问题怎样用python语言解决哇？

Question

两个乒乓球队进行比赛，各出三人，甲队为x，y，z三人，乙队为a,b,c三人。已抽签决定比赛名单，有人向队员打听比赛的名单，x说他不和a比，z说他不和a,c比，编程找出有几种打法？

def pl(ch, seed = ''):
    if len(seed) == len(ch):
        yield seed
    else:
        for c in ch:
            if not(c in seed):
                for x in pl(ch, seed+c):
                    yield x
tema = 'abc'
temb = 'xyz'
vs = list(map(lambda x : zip(x, temb), list(pl(tema))))
for r in vs:
    if r[0] != ('a', 'x') and r[2] != ('a', 'z') and r[2] != ('c', 'z'):
        print(r)

[('c', 'x'), ('a', 'y'), ('b', 'z')]
