Shallow vs Deep Copying of Python Objects

Description

Summary

• But for working with mutable objects or collections of mutable objects, you might be looking for a way to create “real copies” or “clones” of these objects.
• This time we’re going to create a deep copy using the deepcopy() function defined in the copy module instead: Using copy.copy() lets you indicate this fact.
• However, for built-in collections it’s considered more Pythonic to simply use the list, dict, and set factory functions to create shallow copies.
