Hi,

I am not completely sure I understood your question, but as far as I can
tell you are concerned about running python next to C++ (I guess for
performance reasons.)

The core GNURadio application, also the top_blocks are C++ code, so all
the data processing and data passing is done in compiled C++ code (Unless
you decide to write blocks in python of course).
Python is only used for setup and connection purposes and use
automatically generated wrappers for the C++ code (so you call shared C++
libraries from python). See also these two FAQs
