I'd personnaly read this as: "for most concrete cases, there's a Python idiom such that you don't need to set-and-test-at-once" - an example being given for the concrete case of 'iterating over lines in a file'. > I don't know what the Pythonic alternative is.

I guess it's considered the "pythonic alternative" for the concrete use case where there's no better idiom !-) Note that as far as I'm concerned, I don't have much problem with get-and-set (which I commonly use in most other languages allowing it). In fact I'd probably prefer an expression-based version of Python (now would it still be Python is another question...) - but that's not been so far a string enough reason to switch language... -- http://mail.python.org/mailman/listinfo/python-list
