says first task not passing anymore.

lists.py 
the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

The list starts off with 6 items, so the last item, the inner list, is index 5. When you delete two items, now the last item's index is 3, not 5, so you can't do del the_list[5] anymore.

Well, this particular part I'd do with del the_list[3] since that's the last index.

To be honest I used to love programming until it came to the dictionaries lists and tuples, I have no idea what to do in them and I copy the answer from some questions without even understanding them.

Aww, I don't want you to hate programming!

What are some things that confuse you about dicts/lists? Feel free to email me if you want.
