How can I modify nested lists in Python?

How can I modify nested lists in Python?

You can modify nested lists by accessing the elements using their indices. For example, if you have a list like my_list = [[1, 2], [3, 4]], you can change an element like this: my_list[0][1] = 5.

What if I want to add a new element to a nested list?

You can use the append() method to add a new element. For example, my_list[0].append(6) will add 6 to the first nested list.

Can I remove an element from a nested list?

Yes, you can use the remove() method or del statement. For example, del my_list[1][0] will remove the first element from the second nested list.

How do I iterate through a nested list?

You can use nested loops. For example:

for sublist in my_list:
    for item in sublist:
        print(item)
