Hello! i keep getting "Oops, try again. get_class_average([alice]) should return a number".

What i'm doing wrong?


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)
    abc = float(total) / len(numbers)
    return abc

student = [lloyd, alice, tyler]
 
def get_average(student):
    for adc in student:
        homework = average(student["homework"])
        quizzes = average(student["quizzes"])
        tests = average(student["tests"])
        return 0.10 * homework + 0.30 * quizzes + 0.60 * tests
    
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):
    results=[]
    for student in students:
        results.append(get_average(student))
    return results

Thanks in advance!

The problem is exactly what the error says.

You are returning a list instead of a number...


#3

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


#4

I've done that

return average(results)

But get this:

Oops, try again. get_class_average([alice]) resulted in an error: can't multiply sequence by non-int of type 'float


#5

Thank you! Such a basic mistake :slightly_smiling:


#6

I'm getting this error: "Oops, try again. get_class_average([alice]) returned 80.55 instead of 91.15 as expected"

Has anyone had a similar problem? My code is basically identical to lobochefe


#7

same problem... Calculating 80.55 instead of 91.15.

My code looks identical to what is posted.

EDIT: NVM - had
return get_average(student)
results.append(get_average(student))

instead of

results.append(get_average(student))

Can someone explain why I cant do the for loop in two steps like my original?


#8

I think my issue may have been because I had the return statement indented incorrectly. It was not aligned with 'def' which seemed to fix the problem


#9

Had the same issue...thank you! :slightly_smiling:
