Python offers support for object orientation, but it's not an object-oriented language. I mean, you can code a entire program in Python with no classes. So you use it if you want to.
It's not like java, which you must use a class to code a Hello World, but Java isn't fully object-oriented, because it doesn't provide support for multiple inheritance and it has primitive types (multiple interfaces and wrappers to primitive types doesn't count :) ) AFAIK, the unique fully object oriented languagem is Smaltalk. (maybe Simula?), where everything is a class, even the primitive types. An excellent reference book for that is: Sebesta, Robert W.
