How to Slugify a String in Python
Convert any text into a URL-friendly slug using the standard library's unicodedata and re modules.
import re
import unicodedata
def slugify(text):
text = unicodedata.normalize('NFKD', text)
text = text.encode('ascii', 'ignore').decode('ascii')
text = re.sub(r'[^\w\s-]', '', text).strip().lower()
text = re.sub(r'[-\s]+', '-', text)
return text
if __name__ == "__main__":
title = "Hello, Worl…Python: Replace Spaces with Hyphens for Slug

def slugify(text):
return text.strip().replace(" ", "-")
if __name__ == "__main__":

result = slugify(title)
print(result)How to Prefix Python API URIs with a Version Slug
Build a versioned API endpoint by optionally adding a version prefix like v1 to the URL path using the stdlib urllib module.
from urllib.parse import urlparse
BASE_URL = "https://api.example.com"
def build_uri(resource, version="v1"):
"""Mock a versioned API URI with an optional v1 prefix."""
parsed = urlparse(BASE_URL)
prefix = f"/{version}" if version else ""
return f"{parsed.scheme}://{parsed.netloc}{prefix}/{resource.l…Browse by section
