目录

一、功能：

1. 收集全面的系统信息:

2. 提供多种输出方式:

3. 信息组织清晰:

4. 错误处理:

二、运行示例

三、完整代码

四、总结

---

一、功能：

1. 收集全面的系统信息:

基本系统信息(操作系统、版本、架构等)
CPU信息(核心数、频率、使用率等)
内存信息(总量、可用量、使用率等)
磁盘信息(分区、容量、使用情况等)
网络信息(接口、连接数等)

2. 提供多种输出方式:

可以将详细信息保存为JSON文件
可以在控制台打印摘要信息

3. 信息组织清晰:

使用嵌套字典结构组织数据
包含时间戳便于跟踪

4. 错误处理:

对可能失败的操作进行异常处理
确保程序稳定运行

二、运行示例
