what wrong with my code
```

# Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

put your " return average(results) " under "for student in students:" like:

def get_class_average(students):

..... results=[]

......for student in students:

............ s= get_average(student)

.............results.append(s)

.......return average(results)

**tezq**#3

def get_class_average(students):

....results = []

....for student in students:

........results.append(get_average(student))

....return average(results)

This worked for me

You do not need to print results remove this and take away one indent on the return average(results) and it should work
