There are several styles. The most common are procedural
(often also called imperative) and object oriented.
Others include declarative(as personified by Prolog)
and functional.

My web tutor provides a brief description of FP with 
examples in Python. For me the main feature of FP is 
that every statement is an expression that has a value.

Thus the print statement in python is not a valid FP 
construct - it has no value. Lisp, Haskell, Erlang 
and a few others use FP heavily.
