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!
