Maybe funny, but a bit too cocky for my taste. Robert kern is propably right about what he really meant so don't be too hasty in the future, right?). Looking at his code example I got the picture that he's of the kind that could come up with something useful. So either he's right(which I think is the case), or it's just the kind of silly mistake all of us sometimes make. I sure think some one should look in to this suggestion. >>>> class C: > ... def __setattr__(self, e, v): > ... print 'setting %s to %s' % (e, v) > ... self.__dict__[e] = v > ... >>>> o = C() >>>> v = 'mystring' >>>> o.e = v > setting e to mystring >>>> o.e > 'mystring' >>>> > > -Peter -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCweYyctNFyQJObrsRAhGtAJwJXlhQ9i1PIQKj1fus6GIq7mfDVgCeJBRw vq6yJrozRTUSTu+p8akVbVw= =k4EW -----END PGP SIGNATURE----- -- http://mail.python.org/mailman/listinfo/python-list
