functional or object-oriented?

[beza1e1]

I see myself shifting more and more over to the functional kind of
coding. Could be related to the Haskell, we had to learn in CS. Now i
was wondering, how other people use Python?

With functional i mean my files mostly consist of functions and only
rarely i use "class". The library modules seem to be mostly written the
object-way on the other hand.

If you use both paradigms. What are your criterias to choose the right
method for a project?
