I've been developing stuff using ActionScript since AS2,and when AS3 was released i had a bit of a hard time to understand its concepts. Then i realized i had to learn some OOP. I started studying OOP and now i feel i need to take a step further, that's why i chose Python. Are there any tips/advices/hints or whatever like that to help me on this move? Thank you in advance.
--edit--
In other words, what are the differences and similarities between the languages?
