If you're going to do that, you want to run gdb in "machine interface"
mode, which makes it a lot easier to talk to programatically. I've
not done it in Python, but it's easy enough in C, so in Python it
ought to be trivial:
If you don't want to write code to talk the gdb/mi "command language",
then another option is to use a library like libmigdb:
You can probably call the library functions using cytpes:
