You should check out Click. Way more user friendly than argparse imo. I agree with all of your points though, and I’d also add if you are working on a team that it will be infinitely easier for a co-worker to decipher your python code compared to a bash script. And you can write unit tests with py test, the list goes on and on. If the environment you are deploying to has the python interpreter, you should use python over bash.
