@Virelai if it works, it's fine, I guess. Don't usually use subprocess myself. If one-after-the-other is fine for you, a simple shell script might do it. If you want parallel execution (to fully utilize your CPU for example) I'd look at concurrent.futures (in stdlib, I think).
@fabian yeah, it works just fine.
So shell scripts would have been probably the normal way to go, yes? Concurrent.futures sounds handy, I'll check that out! thank you!
