It's Okay To Be Average

Oops, try again. average([3, 0]) resulted in an error: float() argument must be a string or a number

I'm not too sure why it doesn't work but it seems to not be recognising it as a float. Does anyone know how to fix it?


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(grade):
    total = sum(grade)
    grades = len(grade)
    results = total/grades
    float(grade)
    return results

def average(numbers):
    total = float(sum(numbers))
    result = total / len(numbers)
    return result

Sum the grade, convert the sum to a float, then assign it to total, like so:
total = float(sum(numbers))
