Python资源释放+JSON序列化:AI伴侣会话管理核心技术

Python资源释放+JSON序列化：AI伴侣会话管理核心技术 🎯

姐妹们，Day22打卡！

今天学了两块超重要的内容！💪

1️⃣ 资源释放（finally代码块）🛡️

之前学文件操作，有个大问题：

如果程序出异常，close()不会执行，
文件就一直被占用！

解决方案：finally代码块！

无论程序是否异常，
finally里的代码都会执行！

把close()放finally里，
文件一定能正常关闭！✅

2️⃣ JSON模块 📦

AI伴侣的会话数据怎么存？

用JSON格式！结构清晰，
伴侣信息+对话记录一目了然！

核心就两个函数：

• json.dump() → 序列化（写入）✏️
• json.load() → 反序列化（读取）📖

加上ensure_ascii=False，
中文就不会变成\uXXXX了！

会话管理的基础打牢了！
明天继续实战！🚀
