You didn't define the global nom_fichier till after that line.  In 
general, while you're learning, please avoid using the same names for 
global values, class attributes, instance attributes, function parameter 
names, and local variables.   The rules for what a name means changes 
depending on where the name is used.

This is where you got the error, because there's a required argument, 
for parameter nom_fichier.  So you could use
        modele = Modele("thefile.txt")
>>>     nom_fichier = "magasinmodele.txt"
>>>       
I'd call this something else, like  g_nom_fichier.  While you're 
learning, you don't want to get confused between the multiple names that 
look the same.
