The copy() function in Python is a method for dictionaries that returns a shallow copy of the dictionary. This means it creates a new dictionary with the same key-value pairs as the original dictionary. Any modifications made to the copied dictionary will not affect the original dictionary, but changes to nested mutable objects within the dictionary will be reflected in the copy. This function is useful for creating a duplicate of a dictionary without altering the original one.
