Newbie: What is gr-python27

Hi,

I am new to GNU Radio.

I installed it on Windows (8, 64bit) using gnuradio_3.7.9.2_win64.msi.
The installation went smoothly. After that, I found a directory named
gr-python27. Is it different from “regular” Python27, say from Anaconda?

I am looking for an example MSVC project, can someone help with a
pointer?

What is a good starting point for a newbie who prefers C++ on MSVC?

Thanks
