How do I deep copy lists in Python with type hints?

In Python, to deep copy lists while preserving their nested structure, you can use the `copy` module's `deepcopy` function. This is especially useful when dealing with lists containing other lists or mutable objects. Below is an example of how to accomplish this using type hints.

from copy import deepcopy from typing import List def deep_copy_list(original: List[int]) -> List[int]: return deepcopy(original) # Example usage original_list = [1, 2, [3, 4]] copied_list = deep_copy_list(original_list) print("Original List:", original_list) print("Copied List:", copied_list)
