What's the difference between deep copying and shallow copying? I honestly did not know there were different types of copying.

If you have an object and you wish to copy it. There are two ways of copying it - Shallow and Deep. 

The normal copy that we generally use is called Shallow copying which basically creates a new variable and stores the reference of the copied item. It's not a clone or not the real object. Hence any change made to the copy version of an object will be reflected to the original object.

Import copy
list = [1,2,3,4]
list1 = copy.copy(list)

Deep copy, on the other hand, sends a copy of the copied version of the actual object. Hence any changes made to the copy will not be reflected in the original.

import copy
list = [1,2,3,4]
list2 = copy.deepcopy(list)
