Windows process management using Python
提问by Vicky
I need a script that check if a particular process is running and return something if not found. I know that this can be done using subprocess, but is there a simpler way to do it?
我需要一个脚本来检查特定进程是否正在运行并在未找到时返回某些内容。我知道这可以使用 subprocess 来完成，但是有更简单的方法吗？

On Windows, you can use WMI:
在 Windows 上，您可以使用 WMI：
import win32com.client
def find_process(name):
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(".", "root\cimv2")
colItems = objSWbemServices.ExecQuery(
"Select * from Win32_Process where Caption = '{0}'".format(name))
return len(colItems)
print find_process("SciTE.exe")

For similar purposes I have used psutillibrary. Some hints:
出于类似的目的，我使用了psutil库。一些提示：
- list processes with
psutil.pids()(reference) - inspect process information with
process = psutil.Process(pid)(reference) - do
process.killorprocess.terminate()
Installationon windows - pipwill do installation from the source (which means compiling), so you probably want to download binary installation from https://pypi.python.org/pypi/psutil/#downloads.
在 Windows 上安装-pip将从源代码安装（这意味着编译），因此您可能希望从https://pypi.python.org/pypi/psutil/#downloads下载二进制安装。
