The first and main one: don't do it -- it's silly. It's
counter-productive. It's unPythonic. It's the style of
programming that gives programming a bad name.
The second one: if you MUST do it at any cost, look into
sys._getframe, the frame-objects type it returns, and
how from a frame-object you can get at your caller's
local and global variables -- this will let you do this
silliness pretty easily in Python, and the extra mile to
do it from C is really only 800 meters, as it's so easy
for C code to do the equivalent of "import sys", call
the _getframe function of module sys, and so on.
At least, when you're done, you'll have learned a lot
about some of Python's internals and the use of them
from C extension code -- also, this will give you the
time to reflect on whether you really truly want to
do this at all, and hopefully reconsider:-).
