Some are wrong. That style of programming is correctly called procedural 
programming:
http://en.wikipedia.org/wiki/Procedural_programming

Functional programming "is a programming paradigm that treats 
computation as the evaluation of mathematical functions and avoids state 
and mutable data."
http://en.wikipedia.org/wiki/Functional_programming

Many programs can be easily and naturally expressed in a procedural 
style, there is nothing wrong with using it. One of Python's strengths 
is that it supports several styles of programming. There are also 
situations where an OO style yields a simpler, more manageable design. 
This essay gives some reasons why you might want to learn about OO:
