I am not sure in case of Python, but in general, all major operating systems will free the memory upon the termination of process.

Are you referring to the memory that is being dynamically allocated? In C/C++, we use free() function to release the dynamically allocated space (since it doesn't get freed on its own).

Hope that helps

The answer here is no. The modules with circular references to other objects, or to objects referenced from global namespaces, arenít always freed on exiting Python.

Plus, it is impossible to de-allocate portions of memory reserved by the C library.

Whenever Python exists, especially those Python modules which are having circular references to other objects or the objects that are referenced from the global namespaces are not always de-allocated or freed.
It is impossible to de-allocate those portions of memory that are reserved by the C library.
On exit, because of having its own efficient cleanup mechanism, Python would try to de-allocate/destroy every other object.
