# 9. How is Everybody Doing?

I don't know what's wrong with my code. I am so tired... I've looked at all other articles but still..!!

Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

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)
divide = float(total) / len(numbers)
return divide

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 90> score >= 80:
return "B"
elif 80 > score >= 70:
return "C"
elif 70 > score >= 60:
return "D"
else:
return "F"

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)

These lines are indented, inside of your get_class_average function!!
You should be able to unindent them and it be fine, your code looks perfect.

#3

Oh great it worked! Thank you!

#4

Also note that you don't need this line:

but it's fine if you have it. I'm not confident enough to explain it, but I just want to let you know. :)))))) Have a great day!!

#5

After unindenting the three lines to remove them from the scope of the get_class_average function, @chipjumper90361 should not delete this line entirely ...

students = [lloyd, alice, tyler]

The variable, students, still needs to exist as a global object, since it is passed as an argument to the get_class_average function in the two print statements that follow.
