Has an if(cond,exp1,exp2) syntax been considered? It would have the advantage that existing syntax sensitive editors would handle without change. I think conditional exprs badly needed, but the if/then/else syntax seems too verbose for use inside expressions. regards Daniel Mahler Tim Peters writes: > [Paul Svensson] > > ... > > I know there's been a long time request for this feature, > > supposedly from people coming to Python from C, > > but what's the real reason for adding it now, > > without even a PEP ? > > The reason for *considering* it right now is a rapidly closing window of > opportunity -- 2.2b1 goes out later this week.
