The only way you're gonna find out whether it's wise or not is to actually look at some example code and read/do some starters' tutorials. If you've learnt enough to be asking about objects and definition, I don't think you're far from reaching the point where you'll want to/should learn things like PyGame, PyMedia, BeautifulSoup etc.
Get some source code for the simpler games like Tetris from the PyGame website and look at them. That's how I kinda started
