Title: Update Pubnub.py

It seems that the call to presence is just a wrapper around subscribe, hence it should be non blocking (like subscribe) - as opposed to what is written in the comment.
It should also pass the connect parameter to the subscribe call, otherwise, you get an error in the subscribe itself.
