A copy is used to create a replica of an object in python. Python offers two ways of copying called deep copy and shallow copy. Both copy functions are defined under copy class.

Deep copy: Here, the copying process occurs recursively. First, a new collection of objects is created and it is populated with the original object elements recursively. Changes made to the copy are not reflected in the original collection.

Syntax

ListCopy = copy.deepcopy(list1) 

Shallow copy: This works the same as a deep copy but not recursively. The new object is first created and the original elements are copied to it. Any changes made to the copy are reflected in the original element.

Syntax

ListCopy = copy.copy(list1)
