Let me show you an actual zero:
if event.num_attendants: prepare_cake() else: cancel_event()
When no one is coming to your party, is is clearly a different condition than if any number of people are coming to your event. When you read "if num_attendants", you can clearly tell this is going to do something depending on if people are coming or not.
I'm sorry, are you really trying to say that the above code is better than if event.num_attendants != 0: prepare_cake() else: cancel_event() ? (Personally, I'd actually prefer something like "if event.num_attendants > 0" or switch the order of clauses and test for being equal to 0, but that's a minor issue. The major point is I'd prefer any of these to your version). Paul
