Well, I wasn't really talking about 'x and y or z'. I was actually referring to your HUGE incomprehensible one-liner...it wrapped to three lines in my editor. However, the 'x and y or z' idiom is also discouraged because it is NOT the same thing as 'y if x else z'. If it was the same thing then they wouldn't have added that new syntax (which is really ugly IMO, but I digress) to 2.5. The reason they needed a new syntax is because the 'x and y or z' idiom fails if y evaluates to false. Example: x = True y = '' z = 'else' v = x and y or z assert v == y # ERROR! ~ Daniel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
