Thanks Steven, for the reply. Very helpful. I've got a lot to learn in Python :)
Some questions: > (1) Python can automatically free most data structures and close open > files, but if your needs are more sophisticated, this approach may not be > suitable. Since it's a wrapper of a DLL or .so file, I actually need to call mylib_exit() to do whatever cleanup the library needs to do. >> 2. what's the right way to call mylib_exit()?

I'm expecting Python to call it when the program exits. I put a logging line in __del__() but I never see that line printed. It seems that __del__() is not being called even when the program exits.
