This is my first attempt at using asyncio, I don't believe I am using it properly and would like assistance using it to maximize efficiency. The current run time is between 20-22 seconds. I would like to reduce this as much as possible, thank you!

_filePath = os.path.splitext(__file__)[0]+'.exe'

is better expressed as

from pathlib import Path

FILE_PATH = Path(__file__).with_suffix('.exe')

Note that since it's a global constant, it should be capitalized.


Delete username = "".

Password security

Do not use input to capture a password. It's visible to onlookers. Use https://docs.python.org/3/library/getpass.html instead.

Parens and comparisons

if((CS.state).key == 1 and CS.assigned_to == None and CS.u_wi_primary_tech == None):

has a few issues:

  • Don't use outer parens. This isn't Java.
  • Use is None instead of == None since None is a singleton in Python.
  • Don't use parens around (CS.state), either.

Mystery hangs

Why does uninstallApp (which should be uninstall_app) do this?


Don't make your user wait pointlessly.

External processes

Don't use os.system. Use https://docs.python.org/3/library/subprocess.html instead.

More extraneous code


can be deleted.

Expression negation

    if computerInfo["computer"].assigned_to == computerInfo["CS"].requested_for:

should just be

if computerInfo["computer"].assigned_to != computerInfo["CS"].requested_for:
