To answer the question you asked, to convert a list of strings to a list
of ints, you want to do something like:
MODUS_LIST = [int(i) for i in options.modus_list]
But, to answer the question you didn't ask, if you're trying to parse
command-line arguments, you really want to use the argparse module.
It's a little complicated to learn, but it's well worth the effort.
