This returns a string, not a list.  Moreover, lines.extend() is
useless. Replace this with:

def stu_scores():
    with open("file.txt") as f:
        lines =3D f.readlines()
    return lines[11:]

Splitting one character will turn it into a list containing itself, or
nothing if it was whitespace.

This is not what you want it to be =E2=80=94 it=E2=80=99s only a single let=
ter.

Thus it fails here, because ['n'] has just one item, and not nine.
