deep and shallow copy? Interview Question 2024 #codingtips #pythonprogramming

Deep copy and shallow copy are two ways of copying objects in programming, particularly in languages like Python.

Shallow Copy:
In a shallow copy, only the top-level structure of the object is duplicated, and the nested objects are shared between the original and the copy.
Changes made to the nested objects in one will affect the other.
It creates a new object, but any objects inside the original object are referenced, not duplicated.
Shallow copying is faster and requires less memory compared to deep copying.
Deep Copy:
In a deep copy, both the top-level object and all the nested objects are duplicated, creating an entirely new object structure.
Changes made to the original or the copy do not affect each other.
It creates a new object and recursively copies all objects within it.
Deep copying is slower and requires more memory compared to shallow copying.
