Error when running mktorrent subprocess command

[pythonnewbie138]

Thanks for the response.

To address the first part, I should be able to just add the brackets around the list of arguments, right?

subprocess.run(['mktorrent', '-vp', '-s', 'HUH', '-l', piece_size, '-a', 'https://sometracker.org/announce.php', target_file, '-o', torrent_name, final_dest])

With that change, I'm now receiving the following error:

Error:

TypeError: expected str, bytes or os.PathLike object, not int

The only integer in the command is piece_size. Does this mean that there's an issue with the command argument order? I was hoping to avoid that by verifying the expected command worked in cmd.

Your elif block suggestion is great. Thank you!
