Java is usually called an OOP language, because everything you do there 
is put into a class. Free functions don't exist, the closest you get is 
class-static functions (correct me if I'm wrong, I'm not really fluent 
in that language). In Python, you have the choice to use OOP, but you 
can also use free functions or mix those.

As a C++ programmer (roughly 80%C++, 15%Python, 5%C) I know that 
feeling. Having types declared in advance just helps by having the 
compiler check if the passed arguments are correct. Not having this 
gives both freedom but also bears dangers.

You'll get used to it and then start loving it.
