Deep copy creates a new object with the same values as the original, while shallow copy creates a new object with references to the original's values.
Deep copy duplicates all nested objects and their values, while shallow copy only duplicates the top-level object.
Deep copy is more memory-intensive and time-consuming than shallow copy.
Example of deep copy: copying a list of dictionaries using deepcopy() in Python.
