I am so far a bit disappointed by the wiki contents; I'm hoping on more of a summary of the argumentation and use cases; instead, I found wild proposals that have zero chance of making it. > The more I play with it, the more I believe the part I have a problem with is > a weakness in the string formatting for iterables. I've noticed. I think you should cool down a bit about this. Automatically consuming iterables can have serious side effects (like reading a file to the end!), which you generally want to avoid. Putting complex syntax in %xyz format strings for iterators seems like a poor choice of tool -- it is already complex and brittle. All *my* sequence printing needs are generally met by a simple for loop or ",".join(...). If that's still too much typing for you, and you really think that the use case of printing all items in an iterable is common enough to warrant standard library support, I'd suggest something along these lines: def printseq(seq, sep=" ", to=None): if to is None: to = sys.stdout # dynamic default firsttime = True for item in seq: if firsttime: firsttime = False else: printbare(sep, to=to) printbare(item, to=to) # printbare() is just a suggestion; I'm not too happy with the name. > The point about not needing parentheses for conditionals where a lot of other > languages require them is a good one - I'm sure I write print statements > nearly as often as I write conditionals. I'm sad to see that all the good software engineering habits are dropped the moment people have to type a pair of extra parentheses. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
