get_class_average([alice, lloyd]) returned 80.55 instead of 85.85 as expected

always show the same problem. I've tried . i don't know what is the problem

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)
    return float(total) / len(numbers)
    
def get_average(student):    
    homework = 0.1 * average(student["homework"]) 
    quizzes =  0.3 * average(student["quizzes"]) 
    tests =    0.6 * average(student["tests"])
    
    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"

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


#2

why define results inside the loop? This means, each iteration of your loop, results becomes empty again, things you append won't persist

Thanks stetim94. Now work
