# Student becomes the Teacher | 9. How is everybody doing? |

The code appears to be correct but it still prompts me to look for whether or not I am printing the get letter grade function result

``````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]
}

"""Function
The function for calculating the average starts here"""

def average(numbers):
total = sum(numbers)
total = float(total)
result = total/len(numbers)
return result

""" The function to calculate the weighted sum starts here"""

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
test = average(student["tests"])
result = 0.1 * homework + 0.3 * quizzes + 0.6 * test
return result

#Function for printing the letter grade

if score >= 90:
print "A"
elif score >= 80:
print "B"
elif score >= 70:
print "C"
elif score >= 60:
print "D"
else:
print "F"

#Function for calculating the class average:

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)
Change the `print` to `return` in the get_letter_grade function. That should fix things.
