I cannot find my error. It is saying "Oops, try again. get_class_average([alice]) resulted in an error: global name 'result' is not defined"

Hi @orozov ,

In your `get_class_average` function, you have ...

``return average(result)``

Where was the name `result` defined?

Also check the indentation of your `return` statement. It needs to execute after all iterations of the `for` loop have completed.

Thank you @appylpye!
