You must be pretty smart, one could easily extract > a book from that page ;) No, I was being 'conservative'. I am not as smart as the fellow that wrote that MRO paper ;) Honestly, I have had that bookmarked for years... There are some deep conceps on that page and I have not had a 'use case' for most of them. I would gladly welcome the book, you gonna write it!? Something that covers ( with lots of 'real-life' examples ): classes ( I see a lot of questions on c.l.py about basic class use ) special methods and class customization ( putting classes to work ) metaclasses ( what they are and when you might need them ) inheritance ( covering all flavors subclassing,mixin,etc.. ) descriptors ( what are they and why you should care ) types ( creating new ones, subclassing old ones, etc... ) old style / newstyle gotchas for classes / metaclasses and maybe a few pages on decorators.
It is all well and good to have advanced OO in the language, but it would be better if there was a 'reason' for it all. > >I am still trying to grasp the 'purpose' of classmethods. > > In my personal opinion classmethods and staticmethods could (and > possibly > should) be removed from the language; a part for that consideration, > the typical > use for classmethods is as object factories, to provide alternative > constructors. > > Michele Simionato Thank you, I had a feeling that it was just extra fluff. But I felt/feel that way about list comprehensions and decorators too ;) M.E.Farmer -- http://mail.python.org/mailman/listinfo/python-list
