How Is Everybody doing

Oops, try again. Did you remember to print the average of the class? It looks like "[80.55, 91.14999999999999, 79.9, 80.55, 91.14999999999999, 79.9]" wasn't printed. this is the error, but what printed on the return side is

83.8666666667

B

None

My understanding was that we were to get one class average, but I tried it both ways getting an average for each student . I even believe these are the right results.

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