there is no error but I am getting wrong output
Oops, try again. get_class_average([alice]) returned 65.55 instead of 91.15 as expected


Replace this line with your code. ```
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=float(sum(numbers))
    return total/len(numbers)
def get_average(student):
    homework=average(student['homework'])
    quizzes=average(student['quizzes'])
    tests=average(student['tests'])
    return 0.6*tests+0.1*homework+quizzes*0.
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):
    results=[]
    for student in students:
        results.append(get_average(student))
    return average(results)

seems like your quizzes got messed up and left off the .3 on it. Try fixing that! :smiley:

Oops, try again. get_class_average([alice, lloyd]) returned 80.55 instead of 85.85 as expected

here is my code::

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)
return float(total) / len(numbers)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return (homework*0.1) + (quizzes*0.3) + (tests*0.6)

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"

student = lloyd

get_letter_grade(get_average(lloyd))

def get_class_average(students):
results = []
for student in students:
get_average(student)

print get_average(student)

    print results
results.append(get_average(student))
return average(results)

print get_average(alice)
print get_average(tyler)
