google/python-fire ? reverse-engineered prompt

Build me a small Python library that turns almost any Python object into a command line tool.

I want to be able to pass in a function, class, module, dict, list, or object, and have it automatically expose the right commands and arguments from the terminal. It should support a normal help screen, an interactive mode, a way to choose a custom separator for command names, completion scripts for shells, and a trace or verbose mode so I can see what it is doing.

Please include a few simple examples, like calling a function with default values and calling a method on a class from the command line. Also make sure it is easy to install and use in a tiny script with just an import and one call. If you need to check current Python packaging or CLI docs while building it, go ahead and look them up online.
