stuck in this lesson and can't find the way to sort it out even tried all possible ways (from this forum). why I can't print:

<Finally, print out the result of calling get_class_average with your students list. Your students should be [lloyd, alice, tyler].

Then, print the result of get_letter_grade for the class's average>

MY code is:

```
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 = sum(numbers)
total = float(total)
return float(total) / len(numbers)
def get_average(student):
homework = average(student["homework"]) *0.10
quizzes = average(student["quizzes"]) *0.30
tests = average(student["tests"])*0.60
return homework + quizzes + tests
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"
get_letter_grade(student)
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)
students = [lloyd, alice, tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))
```

``please help, I want to get into the next lesson and keep learning python"""`

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