本文目录导读：
我来帮你创建一个统计篮球关门防守（Closeout）成功次数的Python程序，关门防守是指防守球员快速冲向持球进攻球员，阻止其投篮或突破的防守动作。

使用说明
-
基础版本：适合快速统计，主要功能包括：
- 记录每次防守
- 计算成功率
- 按球员统计
-
高级版本：增加更多功能：
- 支持不同防守方式
- 生成JSON格式报告
- 生成统计图表
- 记录进攻球员数据
如何运行
# 保存文件为 closeout_defense.py python closeout_defense.py
这个程序可以帮助统计关门防守的成功次数、成功率，以及分析不同球员和防守方式的效果，你可以根据实际需要调整代码中的记录方式和统计维度。
