What is the method used to create a copy of a dictionary in Python?

The method used to create a copy of a dictionary in Python is the copy() method. This method returns a shallow copy of the dictionary, meaning that it will create a new dictionary object with the same key-value pairs as the original dictionary, but it will not create a deep copy of nested objects.

Using dictionary_name.copy() is a standard and efficient way to duplicate dictionaries in Python, preserving the original dictionary while allowing you to work with its separate copy. This is especially useful when you want to manipulate the copied dictionary without affecting the original data.

Other methods mentioned, such as duplicate(), clone(), and replicate(), do not exist as built-in methods for dictionaries in Python, which reinforces that copy() is the correct and valid approach to copying a dictionary. Thus, the correct answer emphasizes the proper usage of the existing dictionary methods in Python.
