Destroy session in Pylons or Python

I can't find information on how to destroy / kill a session within Pylons or Python on the interwebs. Thought it would be a good idea just to ask it here so that when I need to do it again a year from now I'll find this question :)

So I'm looking for a PHP session_destroy() equ开发者_开发百科ivalent for Pylons or Python.

Thanks, Maggi

session.delete() or session.invalidate(), depending on what you want.
