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

My problem is that the variable total is somehow a list. Therefore, the float function won't work on it.
Any tips?

``````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]
}

def average(numbers):
total = 0,
total = sum(numbers),
total = float(total),
print total,
total1 = float(total)/len(numbers),

at this lines:

``````    total = 0,
total = sum(numbers),
total = float(total),
print total,
total1 = float(total)/len(numbers),

why do you use comma's everywhere?

That was a mistake. I have since taken those out. This does still not change the problem.

you return `total` which contain the total, you store the average in `total1`

you should return the average, not the total/sum

Thank You this fixed it!
