Re: py3k s***s

e Perl 4 was. The cost paid for these minor improvements is too high in my book. But I suppose if it is going to happen do it sooner rather than later. Just *please* *please* don't systematically break the pre-existing code base again for a very long time, preferable ever. -- Aaron Wat

ally or accidentally which means I'll have to carefully rewrite and retest any code which uses the new and improved libraries ... and the "deprecated/removed" libs won't work anymore, so I can't just put them into my package... sigh. -- Aaron Watters === http://www.xfe

Re: py3k s***s

sting code. I really like developing in Python -- but it's hard to keep doing it when the growth curve is so slow and a so many people have deep reservations about it, inspired in part, justifiably, by nonsense like this. In fact, I basically stopped. Then I came back. Now I'm won

Re: Database vs Data Structure?

ho have a "rabbit cage" project -- and if you just pickle everything you will end up traversing the entire database, possibly multiple times to find it. A little old fashioned database design up front can save you a lot of pain. -- Aaron Watters === http://www.xfeedme.com/nucular/pydi

py3k concerns. An example

mple way to translate my code, I think. I suspect you will find this kind of subtle issue in many places. Or worse, you won't find it until after your program has been installed in production. It's a damn shame because if string%dict was just left in it wouldn't be an issue. Also,

Re: py3k concerns. An example

alty (afaik there isn't). An alternative is to provide an alternate interface to string.format so that you could pass in an object which might emulate a dictionary, like string.formatDict(D) -- or you could even adopt a shortcut notation like string % D -- hey there's an idea! -- Aaron Watt
