两个队伍，，a不和x对战，b不和y, z，请写代码实现

实现如下：

#下面有两个队伍，，a不和x对战，b不和y, z，请写代码实现。
team1 = ['a', 'b', 'c']
team2 = ['x', 'y', 'z']
for team1_value in team1:  #战队1循环
    for team2_value in team2: #战队2循环
        if team1_value=='a' and team2_value=='x': #战队1等于a，战队2等于x，不进行输出，继续
            continue
        if team1_value=='b' and (team2_value=='y' or team2_value=='z'):#战队1等于b，战队2等于y或z，不进行输出，继续
            continue
        else: #非上述2种情况，进行输出
            print("%s vs  %s"%(team1_value,team2_value))
