Your project interests me. Actually I was thinking about doing the
same. I hadn't worked on it at all, but I though about it and had the
idea about reading the session namespace directly, which I though
would be stored in the __dict__ attribute of something.

Hello,
This is a question for the best method (in terms of performance
only) to choose a random element from a list among those that satisfy
a certain property.
This is the setting: I need to pick from a list a random element
