FYI: Py2.6 support has ended and Py2 expected to be end in 2020, the countdown is running ;) https://pythonclock.org/ If you wan't a command-line parser which is "builtin" use argparse, this is what I do mostly. If you are able to use requirements from outside use click [1]. For more infos read e.g. [2]. Docopt [3] has its charm but I would prefer the decorators from click.
