The output of the example code is::
Ce code donne le résultat suivant ::
47
After local assignment: test spam After nonlocal assignment: nonlocal spam After global assignment: nonlocal spam In global scope: global spam
After local assignment: test spam After nonlocal assignment: nonlocal spam After global assignment: nonlocal spam In global scope: global spam
48
Note how the *local* assignment (which is default) didn't change *scope_test*\'s binding of *spam*. The :keyword:`nonlocal` assignment changed *scope_test*\'s binding of *spam*, and the :keyword:`global` assignment changed the module-level binding.
Vous pouvez constater que l'affectation *locale* (qui est effectuée par défaut) n'a pas modifié la liaison de *spam* dans *scope_test*. L'affectation :keyword:`nonlocal` a changé la liaison de *spam* dans *scope_test* et l'affectation :keyword:`global` a changé la liaison au niveau du module.
49
You can also see that there was no previous binding for *spam* before the :keyword:`global` assignment.
Vous pouvez également voir qu'aucune liaison pour *spam* n'a été faite avant l'affectation :keyword:`global`.

Really? I had a whole spate of those a couple of weeks back. I wasn't sure if they were spam or not as I was too much of a sdceray cat to click on them!I still wonder if I have inadvertently avoided hooking up with past friends [or possibly foes?]Cheers

Classes introduce a little bit of new syntax, three new object types, and some new semantics.
