Tip on the "Late Binding Closures" section

The two solutions in "What You Should Do Instead" are certainly correct, while there's another solution in that special case, one can simply change

return [lambda x : i * x for i in range(5)]

to

return (lambda x : i * x for i in range(5))

in other words, one can create a generator, rather than a list, to postpone the time when cell contents be evaluated. Actually, a more essential test code could be

for multiplier in create_multipliers():
    print multiplier.__closure__[0].cell_contents

FYI.

Lisez la section "Late Binding Closures", en particulier "What You Should Do Instead", et comparez l’exemple de générateur proposé avec les explications existantes. Exécutez la boucle create_multipliers() fournie pour vérifier le comportement de la closure. Le travail est terminé lorsque la documentation présente correctement toute alternative valide et inclut un exemple clair à l’appui.
