8. Error in def the function - I'm stuck!


#1

Hi you all !

I'm stuck because of a non definited function; however, I'm sure of my code...
Can someone explain, please ?

Have a look below :


#2

I did it !!

I solved il myself :

But pay attention (for french students) : the instructions are to "def calcule_classe_moyenne", with an "e" at the end of "calcule". But when il computes, it only works with "calcul" without an "e" (see above).
After that, it also works with or without an "e".
Navigator bug, maybe...
