9. How is everybody doing?

#1

I am stuck on exercise 9.
My code looks like this:

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]
}

def average(numbers):
total = sum(numbers)
total = float(total)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
total = homework*.1 + quizzes*.3 + tests*.6

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

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

print get_class_average(students)

I am getting the following error message

Traceback (most recent call last):
File "python", line 53, in
NameError: name 'students' is not defined

``Replace this line with your code.``

Is there a line in your code that defines "students"? Is "students" a list?

#3

Back in around lesson 3 we created a students list but for some reason it doesn't carry over so disappears from our code. This throws a lot of people off.

Just under the dictionaries, restore that list...

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