Is there an *easy* way to make an object immutable in python? Or perhaps I should say "one obvious way to do it"? Oughtn't there to be one?
I've found a thread on how to do this[1], which essentially says something like "redefine __setattr__, __delattr__, __hash__, __eq__, __setitem__, delitem__ ... and probably some other stuff too". [1] Yet, what you have to do is pretty mechanical (e.g. all the mutators have to raise NotImplementedError and the hashes and comparisons seem like they have obvious defaults). Given that I have some kind of container, like an overloaded list, and I just say "oh, I need that to be immutable, like a tuple" -- it would be nice to just be able to declare it so. I just want this for QA purposes -- I have a pretty complex system, and I want the programmer to be warned when he accidentally tries to change an immutable enumeration or redefine a symbol. I know a (hard and error-prone) way to do it, but I'm thinking there must be a "smart" way to do it. Is there some way to do that with, e.g. decorators? (I haven't really figured out why I should want decorators, is this a use case?). Or maybe I should make an "Immutable" class, and just inherit from it last so it overloads everything else with the null interfaces? -- Terry Hancock ([EMAIL PROTECTED]) Anansi Spaceworks http://www.AnansiSpaceworks.com -- http://mail.python.org/mailman/listinfo/python-list
