Using subprocess I want to open Windows File Explorer. Then wait for 1 second and close it:
import subprocess, time
subprocess.Popen(r'explorer /select,"D:\tmp\temp"')
time.sleep(1)

1Other than the `terminate()` method? – Ignacio Vazquez-Abrams Dec 29 '16 at 01:14

read [subprocess](https://docs.python.org/3/library/subprocess.html) documentation - there are all information - ie. `kill()` – furas Dec 29 '16 at 01:14

How do you `terminate` or `kill` if `Popen` leaves no `pid` number? – alphanumeric Dec 29 '16 at 01:16

2im pretty sure the issue is that the process is killed almost instantly and it just puts a different explorer instance in the background – Joran Beasley Dec 29 '16 at 01:28

@JoranBeasley, yes this is what happens. If the OP does `p = subprocess.Popen(r'explorer /select,"D:\tmp\temp"');` `print(p.wait())`, it should return print an exit code of 1. – Eryk Sun Dec 29 '16 at 01:34

i think you could run some kind of `taskkill` command against a new Popen ... – Joran Beasley Dec 29 '16 at 01:35

1@Dekel, the new Explorer instance is launched by the DCOM service. It's not a child of the Explorer instance created by `Popen`. – Eryk Sun Dec 29 '16 at 01:43

1If thats the case I don't think you can close it using the PID of the current subprocess you just opened. – Dekel Dec 29 '16 at 01:44
