What is the equivalent of CreateMemStorage() in OpenCV3 in python?

I am referring code from opencv 2.4 and trying to migrate to opencv 3.1. I could not find a complete migration guideline.

CreateMemStorage, as well as many other function to manage dynamic C structures, are now obsolete. This was still present in OpenCV 2.4.12, but is removed in OpenCV 3.

They refer to C api, which was abandoned something like 5 years ago. Now you should use C++ api. As reported from the OpenCV doc:

[CreateMemStorage and similar functions are from] OpenCV 1.x API for creating growable sequences and other dynamic data structures allocated in CvMemStorage. If you use the new C++, Python, Java etc interface, you will unlikely need this functionality. Use std::vector or other high-level data structures.

OpenCV provides a transition guide that can be helpful.
