I'm running calc.exe (windows 10, python 3.6) using proc = subprocess.Popen("calc.exe"), then time.sleep(time) and then want to kill process: os.kill(proc.pid, -9) or os.kill(proc.pid, signal.SIGTERM) gives me error
"Access Denied".
I also tried proc.terminate - it didn't help.
And I also noticed that proc.pid gives different PID from PID which is shown in task manager. Any ideas how to kill my process?
Thanks!
In the python 3 subprocess API, one can kill the child by calling
Popen.kill() which is an alias for Popen.terminate() in Windows (see here). If this doesn't work, you can try
os.system("TASKKILL /F /PID [child PID]")
You can get the PID of the child with Popen.pid()
You can try using windows to kill the process.
command = "Taskkill /IM calc.exe /F" proc = subprocess.Popen(command) or
import os os.system("taskkill /im Calculator.exe /f") If you want to be sure., Try a recursive kill!!
def kill_process(proc): # Check process is running, Kill it if it is, # Try to kill the process - 0 exit code == success kill = "TaskKill /IM {} /F".format(proc) res = subprocess.run(kill) if res == 0: return True # Process Killed else: kill_process(proc) # Process not killed repeat until it is! kill_process('Calculator.exe') 
admin. I had the same problem on windows 10 and had to write this function that does the job..TaskKill /IM calc.exe /F from cmd? (Also try Calculator.exe)
