To-do or not to-do list Final

In this final for my python class in my cyber security focus course, I must make a working to-do list. The list must allow me to add and remove items, as well as mark the items complete. To do this I utilized as little code as possible. I created functions that would add and remove from a dictionary nested in a list. I used the index number of the list to allow me to remove items. As well as to select the key-value pair with the index number then the key of completed and changed the value to True or False, to signify if the item was completed or not.
