足球比赛开始前，A队和B队(每队各11名球员)会依次入场，受场地条件限制，球员通道口每次只能通过一名球员 补充代码，使用多线程模拟入场场景，输出至少5次模拟结果

以下是使用Python多线程模拟入场场景的代码，每个线程代表一个球员：

import threading
import time

class Player(threading.Thread):
    def __init__(self, name, team):
        threading.Thread.__init__(self)
        self.name = name
        self.team = team

    def run(self):
        print("{} from team {} is entering the field".format(self.name, self.team))
        time.sleep(1)
        print("{} from team {} is ready to play".format(self.name, self.team))

if __name__ == "__main__":
    team_a = ["A1", "A2", "A3", "A4", "A5", "A6", "A7", "A8", "A9", "A10", "A11"]
    team_b = ["B1", "B2", "B3", "B4", "B5", "B6", "B7", "B8", "B9", "B10", "B11"]

    players = []
    for p in team_a + team_b:
        if p in team_a:
            player = Player(p, "A")
        else:
            player = Player(p, "B")
        players.append(player)

    for p in players:
        p.start()

    for p in players:
        p.join()

输出结果：
