Slugify function

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

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

Part of Ship MVP

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.

import re


def slugify(inp):
    """Lowercase, collapse every run of non-alphanumeric characters to one
    hyphen, and strip leading/trailing hyphens (ASCII slug)."""
    s = re.sub(r"[^a-z0-9]+", "-", str(inp).lower())
    return s.strip("-")


# slugify("  Hello, World!  ")     -> "hello-world"
# slugify("Node.js & TypeScript")  -> "node-js-typescript"
