Rest of code won't execute until launched programme is closed

I'm launching a programme with subprocess and follow that command with a for loop. The loop won't run until the programme I launched is closed. I don't understand why this is. Could someone please explain?

My Code:

import subprocess
import psutil

subprocess.call('/path_to/programme.exe')
for process in psutil.process_iter():
    print(process)

I'm running Raspbian OS on a Pi 3 (armv7l).

Thanks for your time.

Solution

  • subprocess.call will wait until the command completes. Use subprocess.Popen instead.
