Question: Can no-cover "cover" the rest of the function?

[stdedos]

Is your feature request related to a problem? Please describe.

I have the end of the main() function like so:

    ...

    if args.command == Commands.CMD.value:
        return cmd_handler(j, args)
    
    print(f"Either command '{args.command}' was not handled, or the end of the world is coming!\n", file=sys.stderr)
    parser.print_help(file=sys.stderr)

    return os.EX_USAGE

I'd like to ignore it with a no-cover.

Basically, the rest of the function would be hard to hit (somehow argparse does not "match" command with its function, or dev forgets to return cmd_handler().

I'd like to avoid the if return else pattern since, on top of that, I agree with the https://pylint.pycqa.org/en/latest/user_guide/messages/refactor/no-else-return.html check aesthetically

Any solutions I missed?

Currently there is not a pragma comment that means "ignore the rest of this." The simplest approach that you haven't mentioned is to put that tail of the function into a new function, then you can pragma the call and the function definition with one comment each. It will still look a bit odd though.

Oh yeah - something like def handle_unexpected_main_fallthrough(cmd): # pragma: no-cover

... ofc that will still need the return handle_unexpected_main_fallthrough(cmd), I guess.
But better than nothing, or throwing some "known ignored exception" I guess.

I can go with that. Thank you for the idea 🙃
