Choose Event功能异常：Football全称无法识别，仅缩写F可用

故障原因 #

• 在SportsEvents函数中，用户输入的赛事名称会被强制转为全大写，但events字典里的赛事全称是Football（首字母大写、其余小写），全大写的FOOTBALL不在字典的键列表中，因此触发"Invalid sports event name."错误。
• 输入缩写F时，转为大写后正好匹配字典中的F键，所以流程能正常执行。

修复方案 #

快速修复：兼容全大写赛事名称 #

直接修改SportsEvents函数中Football的判断分支，加入对全大写FOOTBALL的匹配：

elif event_name == "F" or event_name == "FOOTBALL":
    team_name = input("Enter the name of the team: ")
    if team_name in TeamNames:
        events['Football']['participants'].append(team_name)
    else:
        print("Invalid team name.")

通用修复：统一大小写无关匹配逻辑 #

如果希望所有赛事都支持大小写自由输入，可重构SportsEvents的匹配逻辑，避免依赖固定大小写：

def SportsEvents(events, Teams, TeamNames, names):
    event_name = input("Enter the name of the sports event (e.g., Table Tennis, Football, 400m Race or TT/F/400R): ")
    event_input = event_name.lower()

    # 匹配对应的赛事键（忽略大小写）
    target_event = None
    for key in events:
        if key.lower() == event_input or key == event_input:
            target_event = key
            break
    
    if not target_event or events[target_event]['type'] != 'sports':
        print("Invalid sports event name.")
        return

    # 处理Table Tennis/TT
    if target_event in ["TT", "Table Tennis"]:
        participant_name = input("Enter participant name: ")
        if participant_name not in names:
            print("Participant not found. Please enter a valid name.")
            return

        team_name = input("Enter the name of the team (optional, press Enter to skip): ")
        if team_name and team_name in TeamNames:
            events['Table Tennis']['participants'].append(team_name)
        else:
            events['Table Tennis']['participants'].append(participant_name)
    
    # 处理Football/F
    elif target_event in ["F", "Football"]:
        team_name = input("Enter the name of the team: ")
        if team_name in TeamNames:
            events['Football']['participants'].append(team_name)
        else:
            print("Invalid team name.")
    
    # 处理400m Race/400R
    elif target_event in ["400R", "400m Race"]:
        participant_name = input("Enter participant name: ")
        if participant_name not in names:
            print("Participant not found. Please enter a valid name.")
            return

        team_name = input("Enter the name of the team (optional, press Enter to skip): ")
        if team_name and team_name in TeamNames:
            events['400m Race']['participants'].append(team_name)
        else:
            events['400m Race']['participants'].append(participant_name)

优化建议 #

• 新增赛事映射字典统一管理全称与缩写，比如event_map = {'f': 'Football', 'football': 'Football', 'tt': 'Table Tennis', ...}，后续维护更高效。
• 所有涉及赛事名称输入的函数（如AcademicEvents）都采用大小写无关匹配，避免同类问题再次发生。
