When working with lists in Python, you may often need to create copies to manipulate data without modifying the original list. While the copy module provides a convenient way to perform deep copies, it's possible to achieve the same result without importing any external modules. Here's how you can deep copy a list in Python using a straightforward approach:

In the above code snippet, the deep_copy_list function is defined to recursively copy each element of the original list. If an element is itself a list, the function recursively applies the same deep copy operation to it. This process continues until all elements, including nested lists, are copied.

By utilizing this custom function, you can effectively create a deep copy of a list in Python without relying on any external modules. This method ensures that the copied list is entirely independent of the original, preventing unintended modifications.

Whether you're working on a project with minimal dependencies or simply prefer to avoid importing additional modules, this technique provides a straightforward solution for deep copying lists in Python.
