Yeah, i couldn't help but notice the first piece of code is an ugly "switch case". There's a python idiom for this, it's putting your functions in a dictionary and doing something like `cmds_dict.get(args.command, default)(args)`. I guess we all have our religious habits for argument parsing (more of a docopt-er myself).
I guess the author wanted the code to also look friendly to people who are not that familiar with Python - everybody understands a switch, while what you are describing would probably puzzle some people...
