Hi @shreyrupani,

Are you assigning the `list` to the correct name here? ...

``student = [lloyd, alice, tyler]``

Should this be outside your `get_class_average` function? ...

``results = []``

What happens if Codecademy calls your function more than once in order to test it?

Thank you @appylpye
This solves the problem, also, I understood my mistake.
Have a nice day!
