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

.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.

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?

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!
