In which case, maybe you should leave __setattr__ alone for a while.

That's __getattr__.

You need to do things like

class C:
    def __init__(self):
        self.__dict__['spam'] = 'eggs'
    def __setattr__(self, attr, value):
        if attr != 'spam':
           print "it's not spam!"
        self.__dict__[attr] = value

Cheers,
M.
