用python写一段代码，实现校运动会成绩管理系统 该系统可以记录校运动会全部运动项目的成绩、得分和排名情况，系统功能项以菜单形式显示。项目包括 50 米、100 米、200 米、400 米、1500 米、跳高、立定跳远、铅球。 系统可实现的具体功能包括： 1、首先录入各院系在各项目上的成绩及相应的得分（自行设定，如100米成绩12秒内得10分，12-15秒得8分……）。 2、实现按照院系编号输出每个院系的总分。 3、按照总分由高到低对所有院系进行排名。 4、按照单个项目分数由高到低对所有院系进行排名，如按照男子100米成绩对所有院系排名。 5、按照男子总分和女子总高低分别排名。 6、按照项目编号查询各院系该项目的成绩和得分情况。 7、退出系统。

以下是一份Python代码，可以实现校运动会成绩管理系统，具体功能如题目所述：

# 定义各项目得分规则
SCORE_RULES = {
    "50m": {10: 6, 11: 5, 12: 4, 13: 3, 14: 2, 15: 1},
    "100m": {10: 10, 11: 8, 12: 6, 13: 4, 14: 2, 15: 1},
    "200m": {20: 10, 22: 8, 24: 6, 26: 4, 28: 2, 30: 1},
    "400m": {40: 10, 44: 8, 48: 6, 52: 4, 56: 2, 60: 1},
    "1500m": {240: 10, 270: 8, 300: 6, 330: 4, 360: 2, 390: 1},
    "high_jump": {2.0: 10, 1.9: 8, 1.8: 6, 1.7: 4, 1.6: 2, 1.5: 1},
    "long_jump": {7.0: 10, 6.5: 8, 6.0: 6, 5.5: 4, 5.0: 2, 4.5: 1},
    "shot_put": {15: 10, 13: 8, 11: 6, 9: 4, 7: 2, 5: 1}
}

# 定义各院系编号和名称

注意，以上代码只是一个简单的示例，实际情况下可能需要根据具体需求进行修改和完善。
