I literally have no idea what this prompt is asking me to do. I’ve read it over and over and even checked the solution, but it still makes no sense. I’m finding myself hung up with this sentence in particular " The function should double the value of the element at `index`

of `lst`

…"

What does index of lst even mean? They’re both arguments of a function right? What am I missing here? Please help!

Edit: I think I’ve figured it out, but the whole prompt was written in a very confusing manner. I’d still appreciate someone else’s explanation just to make sure I fully understand. Thank you.
