What is the difference between Deep copy and Shallow copy in Python | Python Interview Questions #12
In Python, variables don't store the actual objects, they store the reference to the objects that are in the memory heap. And when we assign
(using = operator) an object to separate variables, the objects do not get copied, but rather, the variables share the same references to the original objects.
Because of this, we need separate module for copying objects in Python, where we will create copies of objects instead of referencing same memory addresses. And here we have two type of copies, Deep copy and Shallow copy.
This is a very famous interview questions, and hope this video will clear out all your doubts regarding deep copy and shallow copy.
