# 6/9 Float Iteration error

#1

<Below this line, add a link to the EXACT exercise that you are stuck at.>

<In what way does your code behave incorrectly? Include ALL error messages.>
get_average(alice) raised the following error: ‘float’ object is not iterable

<What do you expect to happen instead?>
I don’t understand this error at all, there’s no iteration, it just needs to average the list?

```python

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):

return sum(numbers)/len(numbers)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return sum(0.1*homework+0.3*quizzes+0.6*tests)
``````

`sum()` gets you the sum of an iterable like a list. In your case you have numbers only, so you can just add them together using `+`

Thanks so much! Seems obvious now, so an iterable is a thing with commas that you can use a for loop for? Thanks

#4

that is indeed what iterable means, anything that can be looped over
