Managing Windows Processes Using Python

Question

I need a script that checks if a particular process is running and returns something if it is not found. I know this can be done using a subprocess, but is there an easier way to do this?

Answer 1

On Windows, you can use 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")

Answer 2

Take a look at: getting process information in windows

Answer 3

psutil . :

• psutil.pids() ()
• process = psutil.Process(pid) ()
• do process.kill process.terminate()

Installation on windows - pipwill perform the installation from the source code (which means compilation), so you probably want to download the binary installation from https://pypi.python.org/pypi/psutil/#downloads .
