I'm probably not qualified to be much more specific, these links should provide the necessary detail: http://docs.scipy.org/doc/numpy/reference/c-api.html#numpy-c-api http://docs.python.org/c-api/intro.html#objects-types-and-reference-counts http://docs.python.org/extending/newtypes.html The Python interpreter takes care of when to free the memory associated with an object once it's reference count reaches zero. The object reference counts are increased and decreased directly in C code using the Py_INCREF and Py_DECREF macros whenever a new object is created or a new pointer assigned to an existing object.
