本文和大家分享的主要是使用python获取Linux或Windows系统的基本信息相关介绍,希望对大家学习python有所帮助。程序执行后,看起来就像登录Ubuntu Linux系统时提示的motd信息一样,可以看到:
1.系统的类型、发行版本(具体信息)、内核版本等
2.当前系统的时间、时区
3.系统每一个CPU核心的负载和CPU整体负载
4.进程数量
5.根分区的磁盘空间,Windows下默认C盘
6.登录的用户总数和每一个登录到系统的用户的信息
7.内存和交换分区的利用率
8.默认网卡的IP地址
9.系统启动时间和已运行时间
运行截图如下:
(1)Linux下截图:
(2)Windows下截图:
Python代码如下:

已知存在问题:
1.暂时未实现获取Windows下网卡的中文可视名称
2.Windows下的tty名称默认为None,暂时没有设置对用户友好的显示
3.Ubuntu Linux上motd信息的用户登录数量显示为同一用户同一个IP的多个用户视为同一用户,脚本中视为不同用户
4.首次运行可能需要安装依赖的地方库,如psutil、platform、prettytable、netifaces等,请使用easy_install、pip、conda等安装。
5.其他的因为时间原因未指出和未实现的问题,欢迎在文章下面评论留言和在GitHub上提issue
