# Part of the Whole

#1

Oops, try again. get_class_average([alice]) resulted in an error: global name 'result' is not defined

We want to calculate the class average grade.
I removed the PRINT GET_LETTER_GRADE(GET_AVERAGE(LLOYD)) part from earlier in the course, because we don't want that printed (am i correct?), tho this wont solve the code.

So anyone see what's wrong?

``````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 = float(sum(numbers))
result = total / float(len(numbers))
return result

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"])

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

It can't see the students list you are looping for here:

`students = [lloyd, alice, tyler]`

#3

def get_class_average(students):
students = [lloyd, alice, tyler]
results = []
for student in students:
result.append(get_average(student))
return average(results)

Like this? i still get the same error message..

#4

Na... At the bottom of you last function code or maybe after the dictionaries you created.

Like this:

``````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)
