python案例统计任意球直接得分几次？

wen python案例 2026-08-26 192

我来为您编写一个统计任意球直接得分的Python程序,这个程序会分析足球比赛数据，统计任意球直接破门的次数。

    file_stats = parse_match_report("nonexistent_file.txt")  # 将使用示例数据
    file_stats.display_summary()
if __name__ == "__main__":
    main()

使用方法说明：

手动添加数据

stats = FreeKickStats()
stats.add_free_kick_event('Match-001', '梅西', '巴萨', 23, True, 28)

从文件解析

创建比赛报告文件,格式如下：

比赛名称: 第1轮联赛
[皇马] 任意球:C罗,25分钟,直接得分,30米
[巴萨] 任意球:梅西,40分钟,直接得分,28米
[曼城] 任意球:德布劳内,60分钟,未得分,32米

主要功能

count_direct_free_kick_goals(): 统计任意球直接得分次数
get_player_free_kick_stats(): 球员个人统计
get_team_free_kick_stats(): 球队统计
display_summary(): 显示完整报告

输出示例：

==================================================
任意球直接得分统计报告
==================================================
总任意球事件数: 6
任意球直接射门数: 5
任意球直接得分次数: 4
任意球直接得分成功率: 80.00%
--------------------------------------------------
球员任意球得分排名:
  梅西: 2球/尝试2次
  C罗: 1球/尝试1次
  内马尔: 1球/尝试1次
--------------------------------------------------
球队任意球得分排名:
  巴萨: 2球
  皇马: 1球
  巴黎: 1球

这个程序可以根据您的实际需求调整,比如增加比赛日期、联赛等级、进球类型等更多维度，需要我增加其他功能吗？
