Slugify a title in Python

How titles become URL slugs.

import re

def slugify(title):
    slug = title.lower().strip()
    slug = re.sub(r"[^a-z0-9]+", "-", slug)
    return slug.strip("-")

How it works

1. Lowercases and trims the title.
2. re.sub collapses runs of non-alphanumerics into single hyphens.
3. Stray hyphens at the ends are stripped.
