Well, I've checked all the other threads on this topic, applied all those fixes. Still no luck. I'm out of ideas - is there some sort of malfunction going on with the web site?

Formatting gets lost when I copy and paste, BTW.

#3

Hi read this about how to format the code

#4

Thanks for the quick reply. It didn't help.

This is code I copied and pasted from the last time I took the course, 8 months ago. Worked fine then, no reason for it to not work now.

Hi here your code, I will just put it in oder...

1

``````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]
}``````

2

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

3

``````def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])

return 0.1 * average(student["homework"]) + \
0.3 * average(student["quizzes"]) + \
0.6 * average(student["tests"])``````

This part at I add the `print get_letter_grade(get_average(lloyd))` from the lesson 7. Sending a Letter

``````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))``````

1. Here you should add the array of your students .....`students = [lloyd, alice, tyler]` on top of this part like that

``````students = [lloyd, alice, tyler]

def get_class_average(students):
results = []
for student in students:
studentAverage = get_average(student)
results.append(studentAverage)
return average(results)``````

Then in the last lesson 9. How is Everybody Doing? they aske you to do that

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

from your code its this part

``````students = [lloyd, alice, tyler]
print get_class_average(students)``````

2 Then, print the result of `get_letter_grade` for the `class`'s average.
and this part you son't need it.

``print get_letter_grade(students)``

Like you can see I add some part but you code was fine but it was in a wrong order.
Hope that could help YOu
