Use urllib.parse.urlparse() to carve the path from the rest of the url, and posixpath.split() and posixpath.join() to reform the path, and urllib.parse.urlunparse() to put it all back together again.

Out of curiosity, is posixpath necessary? urlparse is always going to return a forward slash.

You don't want to use os.path, since on Windows that will give you ntpath instead.

Is there something wrong with hard-coding a forward slash in this case?

Not per se, but there's no need to; "magic numbers" aren't restricted to numbers.

from urllib.parse import urlparse

def transform(url):
    parsed = urlparse(url)
    return '{0}://{1}/story-print/{2}/'.format(parsed.scheme, parsed.netloc, parsed.path.split('/')[-2])
