#2

in put it together you created a list called students which contains (surprise) your students.

it is missing, add the list again


#3

Traceback (most recent call last):
File "python", line 56, in
File "python", line 29, in get_average
TypeError: list indices must be integers, not str

Getting this error now when i try to print

print get_letter_grade(get_average(students))


#4

your get_average function is designed for a single student, students is your entire class, for this we designed our get_class_average function


#6

its asking me to print the get letter grade though?


#7

yes, of your class_average, so you need to get the letter grade of your get_class_average, not get_average
