You can find a discussion on python design patterns in this previous question.

An implementation of an observer pattern is given here.

Answer 2

There are already some nice sources out there:

Last but not least...Alex Martelli made a very interessting talk regarding this issue in Google TechTalks

Regarding your Observer Question: Online Example not very pretty but a good point to start...
