I want to create 3D animation and also make some big programs. Is python capable of that??? or should I stick to C++????

You can write virtually anything with any language. The questions is, how much C++ or python do you know? If you are great at C++, learning python to code an application would take some time for you to familiarize yourself with the language... It works the same way if you are good at python and wants to write the application in C++.

Now, if you are not good with either, Python is usually easier to get started, so go with that one.

Really, the language you choose to write any application is more often than not, irrelevant. What really might stop your progress is your own knowledge (or lack of) of the language you develop with.

Very specific situations apply, obviously, such as portable devices or hardware drivers, but more often than not, the language you use does not matter...

You can program 3d graphics in both python and C++. C++ program will be much faster/more efficient, but development might take a bit longer. Python program will be more portable, but much slower, and you probably won't be able to create 3d graphics that require a lot of calculations (large particle systems, game engines, etc.). For short mock-up/demo, python will be enough (but if you will be able to make even Quake 1 engine in python, I will be very surprised). For larger CPU-intensive work, C/C++ will be better idea. You can also combine them. Make C++ program and embed python inside.

Here's an interesting alternative you might wish to consider (in addition to OpenGL and all the other Usual Suspects):

IMHO .. PSM

PS:
Which language you choose is mostly a matter of taste. The runtime performance in Python vs. C/C++ will probably be *indistinguishable* from each other. Unless you render your own graphics pixel by pixel, the true bottlenecks will probably be in the graphics library.
