Slugify function

A correct slugify(text) that passes the held-out cases.

You receive: A reviewed slugify function + the passing test report.

Example

A sample of what this play produces. Your result is generated for your inputs.

import re

def slugify(text):
    """Lowercase the text, collapse every run of non-alphanumeric characters
    (spaces, punctuation, underscores, non-ASCII letters) to a single hyphen,
    and trim leading and trailing hyphens. ASCII slug: accented letters are
    separators, not transliterated, so "Cafe au lait" and "Café au lait"
    both end in plain ASCII. Example: slugify("Top 10 Tips") == "top-10-tips".
    Authored for STUD (stud.com) as the play's sample deliverable."""
    slug = re.sub(r"[^a-z0-9]+", "-", str(text).lower())
    return slug.strip("-")

Scope of the check

What's verified: STUD verifies your slugify(text) reproduces the reference slug on held-out cases: the text is lowercased, every run of non-alphanumeric characters is collapsed to a single hyphen, and leading and trailing hyphens are trimmed. Non-ASCII letters are treated as separators, not transliterated, so 'Café au lait' becomes 'caf-au-lait'. STUD does NOT check performance, code style, or any behavior beyond matching the reference output.
