How can I configure MinGW/gdb/python so that I can debug python's C code?

I have downloaded python 3.6.8 with the debugger symbols and executable.

I would like to run it with gdb, as I would like to debug a dll I am loading through ctypes.

I installed Mingw-64, and have gdb.

When I run "gdb python" and then run, it uses python 2.7.9 that came with MinGW.

If I try "gdb ", I get the following:

Starting program: C:\Users\dbak\Python36\python.exe

I am not really sure what I can do in order to debug the version of python 3.6 I have installed.
