How do I use the copy module in Python?

The copy module in Python provides functions to create shallow and deep copies of objects. Would you like to see examples?

Yes, please show me how to create a shallow copy.

You can create a shallow copy using the copy() function. For example:

import copy
original_list = [1, 2, 3]
shallow_copied_list = copy.copy(original_list)

This creates a new list that is a shallow copy of original_list.

What about deep copies? How do they differ?

A deep copy creates a new object and recursively adds copies of nested objects found in the original. Use copy.deepcopy(). Here's an example:

import copy
original_list = [[1, 2], [3, 4]]
deep_copied_list = copy.deepcopy(original_list)

Now, modifying deep_copied_list won't affect original_list.
