How do I copy a list in Python?

You can copy a list in Python using several methods. The simplest way is to use the copy() method.

Can you show me an example of using the copy() method?

Sure! Here's an example:

original_list = [1, 2, 3]
copied_list = original_list.copy()
print(copied_list)  # Output: [1, 2, 3]

What if I want to copy a list with nested lists?

For nested lists, you should use the copy.deepcopy() method from the copy module to avoid referencing the same objects.

Can you provide an example of that?

Absolutely! Here's how you can do it:

import copy
original_list = [[1, 2], [3, 4]]
copied_list = copy.deepcopy(original_list)
print(copied_list)  # Output: [[1, 2], [3, 4]]
