Python advice

[ngangsia akumbo]

I have learned python for some time now. I am developing apps using django. 

I need some advice.
I want to be able to write big programs using python. I have not been able to do that as of now. I need a way forward on what more free ebooks i can get mt hands on so i can accomplish my goals.

I need some advice. should i go on to learn other languages like java or c++ cos i want to be able to using all these knowledge for games, desktop, mobile and web.

i start learning java and i seem it is more real life. it looks real that python.

any advice
