}

print get_letter_grade(get_average(lloyd))

print get_letter_grade(get_class_average(students))


Replace this line with your code.


#2

At your last return statement. Call to results instead of student


#3

return results(student) i made it to this? then i get this error. Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade


#4

You are returning the average of results, right?

return average(results)

Sorry for a quick approach, I have to leave the forums for this day.


#5

results is a value, not a function. Use the average function to arrive at the final return value...

return average(results)

#6

thnx guys but if i use: return average(results) i get the same error

Those three lines need to be unindented so they are not inside a function block.


#9

thnx for the quick reply when i put them all the way back at the side it gives this: Traceback (most recent call last):
File "python", line 52, in
File "python", line 48, in get_class_average
AttributeError: 'dict' object has no attribute 'append'


#10

Did you mean to write 'students' and not 'class_list'?

Did you mean to write, student and not students?


#11

frankly im so confused about this lesson. i think the first one should be student and not class_list but im not sure


#12

I had the same problem. Your logic is correct. Just create a list: students = [lloyd, alice, tyler]. Then in your print statements input students


#13

aprreciate the help but i already have that man :frowning:


#14

To get a class average we need to pass the entire class list (students) to the function. The list is iterated over, one student at a time, during which we call the average() function on each student, in turn.
