A useful method to turn titles into slugs for urls. BSD code from deep in the heart of Django.

slug.py

import re
import unicodedata

def slugify(value):
    """
    Converts to lowercase, removes non-word characters (alphanumerics and
    underscores) and converts spaces to hyphens. Also strips leading and
    trailing whitespace.
    """

    value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore').decode('ascii')
    value = re.sub('[^\w\s-]', '', value).strip().lower()
    return re.sub('[-\s]+', '-', value)
