This line tells you why it doesn't work:

Are you familiar with functions? When you define the function you define it
as taking one parameter:

def grade_score(grade):
    # Code here

but then when you call it:

grade_score()

you don't give it any parameters (or arguments). The traceback tells you
that you need to provide it 1 argument and that you gave it 0 instead.

If you called

grade_score(3, 150)

you would get a similar error, only it would say (2 given) instead.
