Q1: the difference between shallow and deep copy

Shallow copy

Definition : A shallow copy creates a new object but inserts references into the original objects within the original data structure. Changes to nested objects will reflect in both the copied and original object.

Usecase: copy.copy()

Deep copy

Definition : A deep copy constructs a new object and recursively inserts copies (not references) of objects found in the original. This means that changes to the copied object do not affect the original object.

Usecase: copy.deepcopy()
