What is the difference between using .append() and .insert() when adding a new element into the index? What are the different benefits to them?

3

.append() will always be added to the right side of the list.

.insert() can be at any index, which will move the element to the right of the insertion point.

4

But if I put list_name[2].append(“element”) wouldn’t it still be able to be inserted at any index? Could you possibly explain further?

5

We can only implement the .append() method on a list. The code above is treating the third element of a list AS A LIST by implying that that element has an .append() method. Follow?

Ah, I believe I understand now. Thank you!
