I presume this revision would continue to include elif clauses. If I put on a 'designing Python for everyone' hat, then the presence of the leading 'if' looks better than the slightly-too-cute (especially for Python) abbreviated version. +1 >> *If* you want general community input, I would suggest a runoff ballot >> with >> those four choices (and a summary of pros and cons of each), or fewer if >> you see any as unacceptible. > > If there's one thing I've learned from the PEP 308 vote, it is that > votes for language don't work.

If we reject both the status quo and the symbol-tax form and agree on the above as the best wordy form, then it is a moot point anyway ;-) C.l.p. newcomers continue to periodically request "How do I write conditional expressions?". I think most will be happier with something clear and readable. Terry J.
