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

#1

I get an error and I don't have any clue how to solve it.
Sorry for not formatting the code, but I can't figure out how to do it here (already spent 10 min to do so)

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))

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return 0.1 * homework + 0.3 * quizzes + \
0.6 *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 each in students:
results.append(get_average(student))
return average(results)

In the following `for` loop, you are defining each item in `students` as `each` but later try to access it using `student`

``````for each in students:
results.append(get_average(student))
return average(results)``````

Either you use `each` or `student` or anything but stick with it all the way...

``````for item in students:
results.append(get_average(item))
return average(results)``````
