Just started

I have just started using python at work and am rather enjoying it so far, but I have one question. At work we are using a fairly large custom image file format that it represented in most of our codebase as a C++ object. Is there some relativly easy way to access this object in python and, since it is still an evolving object, keep up to date as the object changes? And if so is there a basic tutorial you could point me to?

Thanks!
