As the title says, I am stuck on the lesson "How is Everybody Doing"

Link to the exercise:https://www.codecademy.com/en/courses/python-beginner-en-qzsCL/1/5?curriculum_id=4f89dab3d788890003000096

Every time I click save and submit the error message comes up and states: Oops, try again.

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

How do I fix this? Here is my code:

```
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):
total=0
total=sum(numbers)
total=float(total)
average=total / len(numbers)
return average
def get_average(student):
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):
if score>=90:
return "A"
elif score>=80:
return "B"
elif score>=70:
return "C"
elif score>=60:
return "D"
else:
return "F"
print get_letter_grade(get_average(lloyd))
students=[lloyd, alice, tyler]
def get_class_average(students):
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))
```
