I had a hard time understanding this exersises instructions and whenever I run my code I get this error message: get_class_average([alice]) resulted in an error: unsupported operand type(s) for +: 'int' and 'dict'


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

def get_average(student):
    homework = average(student["homework"]) * .1
    quizzes = average(student["quizzes"])  * .3
    tests = average(student["tests"])  * .6

    return homework + quizzes + 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_average(lloyd))   

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


#2

This line has too much indentation, for one; and, it is passing the wrong object to average. It should be result that is passed in.
