@post 1. Sorry if I find you as an incoerent, because on an other topic, you were bitching about how python is slow for games, and how is performance sucks in audiogames.
But replying to your questions.
1. It depends on what you know. If you know objects it doesn't mean that you are able to use them effectively. You'll be ready to code audiogames when you can master all those things you mentioned.
2. How did I learn python? Well, I read tutorials, since I wasn't satisfacted, I switched to others and ended reading something like 20 tutorials which probably would explain the same thing. I've also practiced with examples, and obviously messed up source codes in the process, pasting the errors on google and finding a fix.
You don't have to read 20 tutorials, like I did. I did it because I am dumb and I needed  to find multiple tutorials.
3. From what I've gathered, pyglet is a library that works more in an OOP manner, than pygame. but since I'm not an expert can't confirm it.  You probably find it difficult because it's more complex than pygame.
What is the difference between socket and twisted?
That's like asking, what's the difference between an house and a brick? Twisted (the house) it's built with sockets (bricks). Twisted is an event driven networking library that allows you to easily create networking applications based on many protocols.
Of course, because my communicating skills are horrible, feel free to send me to fuck off, if you think I've said something wrong, or if you haven't understood what I said.

"I can't use PyOpenAL because It's a low-level library." can you explain what do you mean by this? Also pygame is good for 2d games but if you're looking for games which involve 3d landscape pyglet is the answer. And OpenAL brings hrtf, efx and other effects for implementation. So can you explain why OpenAL isn't a good idea. I am a beginner python programmer myself, and I am learning as I go on.
