# file favcolor.pyfromeasycommandlineimportprogramprogram.version('1.0.1')program.options(('-r','--red'),('-g','--green'),('-b','--blue'),('-w','--white'),)program.parse_argv()ifprogram.red:print('- red')ifprogram.blue:print('- blue')ifprogram.white:print('- white')

$ python favcolor.py -r -w
    - red
    - white
