I am C/C  /Java programmer, but lately I have started learn Python. 
Moreover I have 3D Graphics on my studies. I have to create 3D model of my apartment, with dynamic camera. I am wondering if this is a good idea to merge this two issues, by writing this 3D model in python. 
However as I said, I am a python beginner, so I don't know possibilities, which python can give me in this area. Which libraries/engine will be the best for a start?
If you're solely trying to learn how to do a 3d model go for the language you're the most familiar with. I'd recommend C++ or C# in that case (whichever of the 2 you meant with the second C).
If you also want to learn more about the language Python is the better choice.
But pure language wise I wouldn't say that C++/c#/python beats the other.
Is python is a good choice as language used to implementing my first 3D model?
