# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    return total/len(numbers)
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return homework * 0.1 + quizzes * 0.3 + tests * 0.6
    
def get_letter_grade(score):
    score= float(score)
    if score >= 90:
        return "A"
    elif score >=80 :
        return "B"
    elif score >= 70 :
        return "C"
    elif score >= 60 :
        return "D" 
    else:
        return "F"
        


def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    return  results

step 4 of instructions:

inally, return the result of calling average() with results.

i don't you calling average to calculate the average class grade of list with individual student grades?
