When you are building complex data structures such a form of output could get big really quickly. I've never come across anything like it in any other language that I have used.
The most that's usually required is a __repr__() method that dumps the values of necessary data attributes. > >>The code of the standard library's >>pprint module might be a good place to start > > > I played around with this but it seems more targetted to looking at python > objects as opposed to user-defined. > It is, but it could be used as a basis for something more to your liking. > >>(and the suggested >>functionality might make a nice addition if we could work out exactly >>what the requirement was). > > > I would be glad if people would comment on my example as a step in this > direction. > I'd suggest you instead consider a mixin object that will add recursive data dump functionality to any such classes you require. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://holdenweb.blogspot.com Recent Ramblings http://del.icio.us/steve.holden -- http://mail.python.org/mailman/listinfo/python-list
