Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade


It should move next level


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]
}
student=["llyod","alice","tyler"]

# Add your function below!
def average(numbers):
    total=sum(numbers)
    result = float(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>=90):
        return "A"
    elif(score>=80):
        return "B"
    elif(score>=70):
        return "C"
    elif(score>=60):
        return "D"
    else:
        return "F"
print get_letter_grade(get_average(lloyd))

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

Create your list and then print the results exactly as stated in the instructions. You need to call the list and currently you don't a list.
