Oops, try again. Make sure you have defined get_class_average


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)
    result = total/len(numbers)
    return result
    
def get_average(student):
    homework = average(student['homework'])
    quizzes = average(student['quizzes'])
    tests = average(student['tests'])
    return 0.1*homework + 0.3*quizzes + 0.6*tests
    
def get_letter_grade(score):
    if score > 89:
        return 'A'
    elif score > 79:
        return 'B'
    elif score > 69:
        return 'C'
    elif score >59:
        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 average(results)


#2

your get_class_average should be outside/after your get_letter_Grade function, not nested inside your get_letter_grade function
