足球队联赛

以下是一个简单的示例代码，用于解决足球队联赛问题：

class Team:
    def __init__(self, name):
        self.name = name
        self.points = 0
        self.goals_scored = 0
        self.goals_conceded = 0

    def win_match(self, goals_scored, goals_conceded):
        self.points += 3
        self.goals_scored += goals_scored
        self.goals_conceded += goals_conceded

    def draw_match(self, goals_scored, goals_conceded):
        self.points += 1
        self.goals_scored += goals_scored
        self.goals_conceded += goals_conceded

    def lose_match(self, goals_scored, goals_conceded):
        self.goals_scored += goals_scored
        self.goals_conceded += goals_conceded

    def display_stats(self):
        print(f"Team: {self.name}")
        print(f"Points: {self.points}")
        print(f"Goals Scored: {self.goals_scored}")
        print(f"Goals Conceded: {self.goals_conceded}")


team1 = Team("Team A")
team2 = Team("Team B")
team3 = Team("Team C")

team1.win_match(2, 1)
team2.draw_match(1, 1)
team3.lose_match(0, 3)

team1.display_stats()
team2.display_stats()
team3.display_stats()

运行以上代码，将输出每支球队的积分、进球数和失球数等统计信息。

这只是一个简单的示例，你可以根据需求进行修改和扩展。例如，可以为联赛创建一个League类来管理多个球队，实现比赛安排、积分榜排序等功能。
