it 03. they ask to get average from class list, but the problem is: there is no list called "class".

and another imporant thing: class turns purple, what means its a used as a command.

how am I supposed to solve this? what is the answer?

this is my current code: (I changed the code so It'll be students instead of class,but it returns an error)

```
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]
}
# Add your function below!
def average(numbers):
total = sum(numbers)
return float(total)/len(numbers)
def get_average(student):
homework = average(student['homework'])
quizzes = average(student['quizzes'])
tests = average(student['tests'])
return (homework*0.1)+(quizzes*0.3)+(tests*0.6)
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))
def get_class_average(students):
results = []
for student in students
results.append(get_average(student))
return average(results)
```

when i save that I get : `File "python", line 46`

for student in students
