For best practices for generating URL-safe text strings you should look into pythons secrets module. Specifically the secrets.token_urlsafe([nbytes=None]) function which generates the string randomly. If properly generated the string should be almost impossible to predict or guess.

Here is the usage example for generating a hard-to-guess temporary URL containing a security token suitable for password recovery applications:

import secrets
url = 'https://example.com/reset=' + secrets.token_urlsafe()
