AFAIK, python uses malloc behind the scenes to allocate memory. From the malloc man page... "The malloc() and free() functions provide a simple, general-purpose memory allocation package. The malloc() function returns a pointer to a block of at least size bytes suitably aligned for any use. If the space assigned by malloc() is overrun, the results are undefined. The argument to free() is a pointer to a block previously allocated by malloc(), calloc(), or realloc(). After free() is executed, this space is made available for further allocation by the application, though not returned to the system. Memory is returned to the system only upon termination of the application. If ptr is a null pointer, no action occurs. If a random number is passed to free(), the results are undefined."
