Argh provides a very simple wrapper for argparse.

Argparse is a very powerful tool; argh just makes it easy to use.

Here’s a list of features that argh adds to argparse:

* mark a function as a CLI command and specify its arguments before the parser is instantiated; * nested commands made easy: no messing with subparsers; * infer command name from function name; * infer argument type from the default value; * infer argument action from the default value (for booleans); * infer arguments from function signature; * add an alias root command help for the --help argument; * enable passing unwrapped arguments to certain functions instead of an argparse.Namespace object.

Argh is fully compatible with argparse. You can mix argh-agnostic and argh-aware code. Just keep in mind that dispatch() does some extra work that a custom dispatcher may not do.

This package installs the library for Python 3.
