Exceptions (despite the name) are absolutely *not* "exceptional" in Python; they're the standard idiom for handling all sorts of things. The "Pythonic" idea isn't "Look Before You Leap" (check first, then act); it's instead "Easier to Ask Forgiveness than Permission" (try to do something, and handle failure if it does happen). Love your exceptions; they're friendly (and quite useful) beasts. -- You received this message because you are subscribed to the Google Groups "Django users" group.
