Once again I'm in the dark. code looks right but error message says:

Oops, try again.

Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.

and I have a print statement but it won't print out.

```
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): #this function gets averages
total = sum(numbers)
float(total)
average = total / float(len(numbers))
return average
def get_average(student): #this function gets average for h,q,t
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): # this function gets total average
if score >89:
return "A"
elif score >79:
return "B"
elif score >69:
return "C"
elif score >59:
return "D"
else:
return "F"
def get_class_average(students):
students=[lloyd, alice, tyler]
results = []
for student in students:
results.append(get_average(student))
return average(results)
print get_class_average(students)
print get_letter_grade(get_class_average(students))
print results
```

What's wrong?
