What is deepcopy in Python and how do I use it?

Can you explain what deepcopy is in Python?

Sure! In Python, deepcopy is a function from the copy module that creates a new object that is a deep copy of the original object.

How is deepcopy different from a regular copy?

A regular copy creates a new object but does not create copies of nested objects. Deepcopy, on the other hand, recursively copies all nested objects.

Can you give me an example of using deepcopy?

Of course! Here's a simple example:

import copy
original_list = [1, 2, [3, 4]]
deep_copied_list = copy.deepcopy(original_list)
original_list[2][0] = 'changed'
print(deep_copied_list)  # Output: [1, 2, [3, 4]]
