Part of the Whole - error in my exercise


#1




I get the following error message:

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected


I'm not able to understand what i've done wrong. Can you please help me?


lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]

    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],

# Add your function below!

    elif score>=80:

        return "F"
        
print get_letter_grade(get_average(lloyd))

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


#2

a function ends the moment a return keyword is reached, if a return keyword is reached in a loop, the loop will break in order for the function to end

place return outside the loop so the whole loop can run, and doesn't break in its first iteration


#3

place the return outside the loop

Got it. Thank you :slight_smile:
