You can also use textwrap to wrap the comments

#!/usr/bin/env python3
__doc__ = '''program wrapcomment.py
'''
__version__ = '0.0.1'
import argparse
import token
from tokenize import tokenize
import textwrap

def spit_comments(filename, width):
    with open(filename, 'rb') as ifh:
        for tok in tokenize(ifh.readline):
            if tok.type is token.COMMENT:
                s = textwrap.fill(tok.string, width=width)
                print(s)

if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        description = """\
Applies textwrap to all the comments in the argument file
and print these comments to stdout.
        """)
    parser.add_argument('filename', metavar='PYFILE',
                        help='python program to scan.')
    parser.add_argument('-w', '--width', metavar='WIDTH', type=int, default=70, help='textwrap width')
    args = parser.parse_args()
    spit_comments(args.filename, width=args.width)
