get_class_average([lloy]( returned 85.85 instead of 80.55 as expected.


I expected the task to complete.


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]
}

# Add your function below!
def average(numbers):
    total=sum(numbers)
    total=total/float(len(numbers))
    float(total)
    return total
    
def get_average(student):
    homework=average(student["homework"])
    quizzes=average(student["quizzes"])
    tests=average(student["tests"])
    return tests*0.6+quizzes*0.3+homework*0.1
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"
    print score
    
results = []
def get_class_average(students):
    for student in students:
        result=get_average(student)
        results.append(result)
    return average(results)

Hello @boardplayer44375,

You only need to return result in the get_class_average() function. Hope this fixes your problem...


#3

Er.. I don't get it. Is that not what I already am doing, here:
'''
return average(results)
'''


#4

No, the task tells me to:
"Finally, return the result of calling average() with results"

"result" variable contains a single number from the student average. Task requires me to return the average of student averages which I think are stored in a list of results.


#5

You are right, @boardplayer44375. But the results list should be defined inside the function. That should definitely make it work!


#6

Holy mother of jesus that worked. Why?
Does program flow skip the step somehow if it's before the function def? Why?


#7

Oh I guess it's because functions have their own tree of variables/lists/dictionaries.
