Context: I am writing an application that accesses XMP-coded files. Some fields contain dates, and comply to iso 8601. I installed the iso8601 python module (http://cheeseshop.python.org/pypi/iso8601), it fails on the simplest forms: ipdb> parse_date('2005-01-01') *** TypeError: expected string or buffer (behaves fine with complete strings, but this one is legal!) Choose a module Python interfaces to the world: very few libs or protocols have no python module interfacing them. But they sometimes have many, and it aint easy to pick up the right one. And if there is only one, it aint obvious wether it will fill your quality criteria. My dream: a table with, for each library/module or even application, a note in [0:10] in front of every quality criterium. criteria?: completeness robustness how well tested? simplicity documentation maintenance team responsiveness usage: how many developpers picked it up and still use it? how many picked it up but gave it up? The list is an obvious oversimplification, each criterium could be discussed for hours. robustness, for instance, means: how well does it behave when illegal data is fed? A LOT of actual modules (comprising mine (:-) raise obscure exceptions. the iso8601 module is simple enough, easy to install, but fails on legal data. I guess the fix would be useful, but is it maintained? Is it in use? I used xml.dom.minidom, recently. Works fine, but I found the interface awfully complicated. Right or wrong, when I had to write some xml, I wrote my own code: better be simple, although untested, undocumented, etc, than using a module so complicated U never finished the learning curve... So, my questions would be: - how do You, other developpers, cope with this question? - is there such a base, helping to pick up existing modules? - if no, dont U think such an initiative might be useful? - Those who have to deal with iso8601 dates, how do U proceed? Ill have a look to mxdatetime, but is it the right answer? -- http://mail.python.org/mailman/listinfo/python-list
