I believe the code is doing what I think it should do, must be a misunderstanding

How Is Everybody doing


Oops, try again. Did you remember to print the average of the class? It looks like "[80.55, 91.14999999999999, 79.9, 80.55, 91.14999999999999, 79.9]" wasn't printed. this is the error, but what printed on the return side is

83.8666666667
B
None


My understanding was that we were to get one class average, but I tried it both ways getting an average for each student . I even believe these are the right results.


lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]
}
alice = {
    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],
    "tests": [89.0, 97.0]
}
tyler = {
    "name": "Tyler",
    "homework": [0.0, 87.0, 75.0, 22.0],
    "quizzes": [0.0, 75.0, 78.0],
    "tests": [100.0, 100.0]
}
students = [lloyd, alice, tyler]
results = []
def average(n):
    total = sum(n)
    total = float(total)
    result= total/len(n)
    return result
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    grade = 0.10*homework + 0.30*quizzes + 0.60*tests
    return grade
    
def get_letter_grade(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):
    for student in students:
        results.append(get_average(student))
    return results




student_ave = get_class_average(students)
class_average = average(results)
letter_grade = get_letter_grade(class_average)
print class_average
print letter_grade


#2

your get_class_average doesn't behave as it should


#3

It returns the averages for the 3 students. I thought that was what it was supposed to do? Am I also supposed to be averaging the results and return that class average? and then from that get a letter grade?


#4

The name is get_class_average, not get_class_averages

It also has the problem that calling it affects its future results. Go back to the previous exercise, pretty sure it doesn't pass your current code


#5

It worked fine after I returned one class average for the individual students instead of the individual student averages. then I called the the funciton for getting the letter grade. Thanks for the hint.
