What's happening is the basic application of name binding in Python: --> C = anything whatever C was bound to before, it no longer is, because now it is bound to . What you are trying to do is mutate C, not rebind it. As Dave suggested, you can use slice notation ([:]) or some method of C (that you create) to do so. > Basically i'm asking how to override, if i can, the `=` You can't. ~Ethan~
