It's Okay to be Average

Error: Oops, try again. get_class_average([alice]) should return a number


Not sure why alice isnt returning a number?


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 = float(total) 
    return total / len(numbers)
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    
    weighted_avg = (.1 * homework) + (.3 * quizzes) + (.6 * tests)
    return weighted_avg
    
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 get_letter_grade(get_average(lloyd))

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


#2

Remember to return the average of results.


#3

Oops, try again. get_class_average([alice]) returned 80.55 instead of 91.15 as expected

with updated code:

def get_class_average(students):
   students = [lloyd, alice, tyler]
   results = []   
   for student in students:
        results.append(get_average(student))
        return average(results)

#4

Now you have to check your indents for a little. Is everything correct in the intendation of your for- loop?
Also the students- list seems to be very useless (and it's name is a parameter of your function), maybe you should remove it?

print get_letter_grade(get_average(lloyd))

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

updated code, removed the list and indents seem fine to me?
error: Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

which is different than before


#6

It looks like you didn't change the indents at the last function! Check the indents again, there's one naughty indent messing up your funtion.


#7

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

:slight_smile:lol the return haha thanks for your patience and not giving it away! Much appreciated!

No problem, nice that you got it! :slight_smile:
