My advice would be to start somewhere - anywhere - and you'll gradually get a more solid grasp on what you want to learn. I'm not familiar with Python personally, the first language I dipped my toe into was Java and then C#. And don't expect to be producing AAA titles any time soon. There's a reason why they cost hundreds of millions to develop!
It doesn't matter particularly where you start, the fundamentals of programming are largely transferrable. But it's no short journey! If you have no background in programming and just want to start making games, you may be better served looking into something like Game Maker or RPG Maker to get a feel for games development, and then look at learning a "real" programming language (forgive the awful terminology) once you've got your feet wet.
I started out tinkering in Multimedia Fusion 2 back in high school. I never produced anything significant (less to do with MMF2 and more to do with being an extraordinarily easily-distracted teenager), but I got a flavour of games creation (albeit in a contained environment), and most importantly it was a lot of fun. Last year, I looked into XNA and learnt C# to be able to make use of that, and then decided I wanted to go a little deeper - learning C++ and DirectX.
Wherever you start, it will be a journey. Quite a long one! There's few shortcuts, but the journey is a lot of fun. Start out small, and see where it takes you.
