I wrote the below code

    def process(match):
        word = match.group('word')
        randomStr = ''.join((random.choice((string.ascii_uppercase + string.ascii_lowercase)) for _ in xrange(random.randint(6, 12))))
        if ((word.upper() in kb.keywords) and (word.upper() not in IGNORE_SPACE_AFFECTED_KEYWORDS)):
            return match.group().replace(word, ('%s%%23%s%%0A' % (word, randomStr)))
        else:
            return match.group()
    retVal = ''
    if payload:
        payload = re.sub('(?<=\\W)(?P<word>[A-Za-z_]+)(?=\\W|\\Z)', (lambda match: process(match)), payload)
        for i in xrange(len(payload)):
            if payload[i].isspace():
                randomStr = ''.join((random.choice((string.ascii_uppercase + string.ascii_lowercase)) for _ in xrange(random.randint(6, 12))))
                retVal += ('%%23%s%%0A' % randomStr)
            elif ((payload[i] == '#') or (payload[i:(i + 3)] == '--    ')):
                retVal += payload[i:]
                break
            else:
                retVal += payload[i]
    return retVal

What's a good function header?
