One common technique is to divide the heap's memory space into three generations based on an object's longevity: All newly created objects start in the first generation. Short-lived objects, such as temporary variables, never make it out of this generation. The garbage collector identifies them...
Keep in mind, this is only simulates pointer behavior and does not directly map to true pointers in C or C++. That is to say, these operations are more expensive than they would be in C or C++. Remove ads Using Python Objects The dict option is a great way to emulate pointers in Py...
