本文实例讲述了Python获取系统所有进程PID及进程名称的方法。分享给大家供大家参考，具体如下：

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，顺便看看本机Windows7系统中到底运行着多少个进程，进程都是什么。

代码：

# -*- coding: utf-8 -*-
#! python2
#!/usr/bin/python
import psutil
pids = psutil.pids()
for pid in pids:
  p = psutil.Process(pid)
  print("pid-%d,pname-%s" %(pid,p.name()))

运行结果：

pid-0,pname-System Idle Process
pid-4,pname-System
pid-288,pname-smss.exe
pid-428,pname-csrss.exe
pid-480,pname-wininit.exe

pip install psutil
