How do I nest lists in Python?

Nesting lists in Python means creating a list that contains other lists. You can do this by simply including lists as elements within another list.

Can you show me an example?

Sure! Here's a simple example: nested_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]. This creates a list with three sublists.

How can I access elements in a nested list?

You can access elements using multiple indices. For example, nested_list[0][1] will give you 2, which is the second element of the first sublist.

What if I want to add another list to the nested list?

You can use the append() method. For example, nested_list.append([10, 11, 12]) will add a new sublist to the end of nested_list.
