Can anyone elucidate exactly what the course_grader function call is passing to the course_grader function using the ([n, n, n]) argument, and how the course_grader function is storing those parameters using a non-specific variable called “test_scores”?

It looks to me like it is passing an array(list), but i don’t recall that being covered to this point.

I’m presuming I will somehow have to iterate through the values of the parameter set and add them to an accumulator variable to determine the sum, and then somehow determine the length of the parameter set in order to determine an average. I understand the logic of the problem perfectly well–it’s the secret knowledge of the syntax that is making this exercise overly time consuming.

Enlightenment would be helpful…thanks in advance.
