optparse is so old-fashioned. Use plac!

$ cat x.py
import plac

@plac.annotations(
    lines=('number of lines', 'option', 'l', int),
    topbottom=('T(op) or B(ottom)', 'option', 't', str, 'TB'))
def main(arg, lines=10, topbottom='T'):
    print arg, lines, topbottom

if __name__ == '__main__':
    plac.call(main)

$ python x.py -h
usage: x.py [-h] [-l 10] [-t T] arg

positional arguments:
  arg

optional arguments:
  -h, --help           show this help message and exit
  -l 10, --lines 10    number of lines
  -t T, --topbottom T  T(op) or B(ottom)
