What is the difference between a deep copy and a shallow copy in Python?

A shallow copy creates a new object but doesn’t create a copy of nested objects, instead it just copies the reference of nested objects.

A deep copy creates a new object and recursively adds the copies of nested objects present in the original elements. It means that any changes made to a copy of object do not reflect in the original object.

copy.copy() function is used for shallow copy and copy.deepcopy() function is used for deep copy.
