CLIs with Argparse or Click

Argparse or Click?

Argparse is a standard library module. It is easy to get started with it, but you also notice the age of the API. More modern libraries like Click make it easier to handle complex data types and create command line apps with sub commands.

You can use argparse if you just want to create a simple CLI without adding extra dependencies.

If you want to build a larger, more complex application, Click maybe more appropriate.

But the most important thing is: choose the framework you feel most comfortable with.
