i don't have idea why this code throw this error

``````lloyd = {

"tests": [75.0, 90.0]
}
alice = {

if score >= 90.0:

return "D"
else:
return"F"

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

This was a very tricky one I must say but apparently it was that your parameter needs to be students not student or else you won't get the right results on the console.
