I'd like to build a database wrapper using DictMixin and allow items to be appended by my own code. The problem is += is always understood as setitem and getitem plainly.d = MyDict() d['a'] = 1 # this is the problem code that's I'd like to override. It's always setitem('a', getitem('a') + 3) d['a'] += 3 # i wanted to do something like my own 'appenditem' function which for example could be useful if getitem is an expensive operation which can be avoided. I hope that was clear enough of a request, it's really late at night here...
I'm sorry, this is just part of the syntax of Python. You cannot override it. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
