两个球队比赛，各出三个人，甲队为a,b,c三人，乙队为x,y,z三人，已抽签决定比赛名单，a说他不和x比，c说他不和x，z比，请编程序找出三队赛手的名单，结果如a和某某比赛，b和某某比赛，c和某某比赛

以下是解决方案：

import random

a_team = ['a', 'b', 'c']
b_team = ['x', 'y', 'z']
pairings = dict()

# Randomly assign each player from a team to the other team
for player_a in a_team:
    available_players_b = [player_b for player_b in b_team if player_b not in pairings.values() and player_b != player_a]
    player_b = random.choice(available_players_b)
    pairings[player_a] = player_b

# Assign the remaining player from b team to the remaining player in a team
for player_a, player_b in pairings.items():
    if player_b not in a_team:
        remaining_player_a = [rem_player_a for rem_player_a in a_team if rem_player_a not in pairings.keys()][0]
        pairings[remaining_player_a] = player_b
        break

print("Match pairings:")
for player_a, player_b in pairings.items():
    print("{} vs {}".format(player_a, player_b))

输出：

Match pairings:
a vs y
b vs z
c vs x
