Earlier quoted context omitted.

This is more of a packaging problem. There are various ways to package python code with it's dependencies into a single executable. In any case, comparing a stdlib library to a 3rd party one is a bit apples to oranges. Most people first decide whether or not they want to use pypi packages, and then start evaluating which ones are appropriate.

sure, if you're building a CLI to do management commands for an application that already has dependency management in place, that's all fine but if you just have some basic script to scrape some logs or zip up files, its nice to have it be self contained

I'm not sure why click is often recommended. I've used argh for years and find it easier: def hello(name): return "hello {}".format(name) def ping(): return "pong" if __name__ == "__main__": import argh parser = argh.ArghParser() parser.add_commands([hello, ping]) parser.dispatch()

If people in your organization tend to write Flask apps, then you might find click in standalone scrips as well.

The thing that bugs me about click is that now your python script has a python dependency that you have to install every time you need to run the script. This is fine sometimes, but a lot of the time I want a script that will be usable with minimal setup, which is why I always use argparse, which is in the standard library, and gets the job done despite its quirky API.
