chime: You can run Python from the command line too, which is also why you can run Chime from there as well.
python -c "import time; time.sleep(1)"
Even if we were running a script from the command line we'd like to get our notification, so we need to add an & to chain the commands.
python -c "import time; time.sleep(1)"
The setup below will play a sound regardless of the fact that the first command succeeded or not.
# This is preferable on MacOS/Ubuntu
python -c "import time; time.sleep(1)"; python -m chime
# This is preferable on Windows
python -c "import time; time.sleep(1)" & python -m chime
