How do I deep copy lists in Python for production systems?

In Python, deep copying lists is crucial for production systems where you need an independent copy of the original list, ensuring that changes to one do not affect the other. The `copy` module provides a straightforward way to achieve this using the `deepcopy()` function. This method is particularly useful when you have complex nested lists.

Here’s an example of deep copying a list:

import copy original_list = [[1, 2, 3], [4, 5, 6]] deep_copied_list = copy.deepcopy(original_list) # Modifying the original list original_list[0][0] = 'changed' print("Original List:", original_list) print("Deep Copied List:", deep_copied_list)
