try this code:

}

def average (numbers):

return result

Thank you enigmatikos. I couldnt run your code either as 'return is an external' other indentation erros are popping up.

Appreciate if I get helped in identifying whats wrong with the code i pasted originally? Invalid syntax is too cruel an error to bear for such beauituful code :blush: ...Thank you


#4

in which part of "student becomes the teacher" are you?

8th?


#5

Right, enigma, its part 8, "part of the whole" . Thank you.


#6

i copied your code in my part 8 and it works fine.


#7

remember to include also this line of code

students = [lloyd, alice, tyler]


#8

right, i just did. Thank you. i was wondering all the while, where codecademy got 'students'list defined..perhaps its was "built-in" for the tutorial is what i thought --- an example of a budding programmer losing common sense :smile: ...Thank you.... Are you in the states? its really early
