Oops, try again. Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.


I was hoping it would print the grade & average score of all 3 students.
When i put in their names into where "students" it says only 1 argument allowed, or students not defined.
can any one help ? would be much appreciated.


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)
    average = total / len(numbers)
    
    return average
    
    
    
def get_average(student):
        
        homework = average(student["homework"]) 
        quizzes = average(student["quizzes"]) 
        test = average(student["tests"]) 
        return 0.1 * homework + 0.3 * quizzes + 0.6 * test
        
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"
    elif score <= 60:
        return "F"
        
    print get_letter_grade(get_average(lloyd))
    

def get_class_average(students):
    students = lloyd, alice, tyler
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results) 
    
    
def students(lloyd, alice, tyler):
    print get_class_average(students)
    print get_letter_grade(get_class_average(students))

I think, you don't need this function:

try this instead:

students = [lloyd, alice, tyler]

print get_class_average(students)
print get_letter_grage(get_class_average(students))
