Sure here is:

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

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"
average = get_average(lloyd)
print get_letter_grade(average) 


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

that took me longer to find then i like to admit, here:

average = get_average(lloyd)

this will overwrite your average function, so now when calling average here:

average(student["homework"])

you have a problem. remove this lines:

average = get_average(lloyd)
print get_letter_grade(average)

Thanks Man, it worked fine by changing the average variable to average1. Really Appreciate your effort.
