使用python获取系统所有进程PID以及进程名称

psutil模块中提供了进程管理方法，引用其中的几个方法就能够获得进程的相关信息。简单写个小脚本测试一下，顺便看看我的Mac中到底运行着多少个进程，进程都是什么。

代码：

  1 #!/usr/bin/python

  2 

  3 import psutil

  4 

  5 pids = psutil.pids()

  6 for pid in pids:

  7     p = psutil.Process(pid)

  8     print("pid-%d,pname-%s" %(pid,p.name()))

  9 

 10 

运行结果如下：
