Sending a letter

This error comes up
Oops, try again. get_letter_grade(89) returned 'A' instead of 'B' as expected.


I have been stuck on this for a bit, and tried to search the forums but no one else seemed to have the same problem. I also tried using score = get_average(student) but that gave the error of global message 'student' not defined. -_-

    "tests": [75.0, 90.0]

# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = total / len(numbers)
    return total

def get_average(student):
    homework = average(student['homework'])
    quizzes = average(student['quizzes'])
    tests = average(student['tests'])
    total = .1 * homework + .3 * quizzes + .6 * tests
    return total
    
def get_letter_grade(score):
    score = get_average
    if score >= 90:
        return 'A'
    elif score >= 80:
        return 'B'
    elif score >= 70:
        return 'C'
    elif score >= 60:
        return 'D'
    else:
        return 'F'
print get_letter_grade(lloyd)


#2

This line may be removed. We need the score that is passed into the function.


#3

You need to change the parameter of the get_letter_grade function from 'score' to 'student'.
Then inside the function:

score = get_average(student)

The reasoning behind your problem is that you were calling your get_average function, without any parameter


#4

Worked, but I am still not clear as to why? How does it know what to use for score? or is it a python thing that always will be?


#5

I tried that earlier before posting, it seemed logical to me


#6

That does not jive with the error message:

score is the correct parameter according to the above.

We do not pass a student dictionary, but the calculated average for that student.

get_letter_grade(get_average(lloyd))

would fit into that scenario.

My sincere apologies for my misleading post.
