1. Abstract process11,000 things are objects: Any conceptual component (dog, building, service, etc.) in a program can be represented as an object1.2 Programs are collections of objects that call each other by sending information to each other1.3
Python memory management is implemented by reference counting. When the object's reference count is 0 o'clock, it is reclaimed by the GC.To explore the storage of objects in memory, we can resort to Python's built-in function ID (). It is used to
