unused import argparse

I took a look into your code and as I can see you import argparse and getopt but only using one of them (getopt).

Also I recognized that you are providing the help output by a function get_help() via the docstring.
It may be easier to do so using argparse instead of getopt, cause this module has the benefit of creating a help description output way more dynamically so you can easily add or remove options.
