使用Python结束外部程序

Question

I'm writing a program that needs to be able to kill certain processes. The two lines I'm currently using work; however, the second line os.system(task) launches command prompt for a split second whilst it's ending a process. Are there any equivalent lines which do not launch command prompt?

Snippet :

task = 'taskkill /im ' + taskname + ' /f'
os.system(task)

This is in Windows 7 if you couldn't have guessed.

Answer 1

Try using subprocess.check_call instead of os.system . This won't launch the process in a console window.

import subprocess
taskname = '...'
task = 'taskkill /im ' + taskname + ' /f'
subprocess.check_call(task, shell=True)
