Hey guys please help me out am stuck at #Just weight and see

Am getting an error message ......."Oops, try again. get_average(alice) raised the following error: 'float' object is not iterable...."

Here's my code,

def get_average(student) :

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["tests"])

```
weight = homework * .1 + quizzes * .3 + tests * .6
return sum(weight)
```

where's the problem?
