Please help. I'm stuck on the lesson "Student Becomes the Teacher"

The console box says none, but I get the following error: **Oops, try again. get_class_average([alice]) should return a number**

I have tried a number of different things and looked through the forums. Nothing seems to work. Any help would be appreciated.

**Thank you! I was able to fix the problem.**I took out the students list. I also separated results.append() from return average(results) I think the second part did the trick. I'm not sure the students list mattered. ****

```
def get_class_average(students): #defining the function
students = [lloyd, alice, tyler] #list containing my students
results = [] #empty list for results
for student in students: #for loop
get_average(student)
return results.append(get_average(student))
def get_class_average(students): #defining the function
results = [] #empty list for results
for student in students: #for loop
get_average(student) #per instructions
results.append(get_average(student))
return average(results)
```
