Hi, I am writing an interface module with the PARI library and I had the same question. So I implemented division operator for my new type which of course did not work if both division arguments are integers. Say 3/4 gives zero. But I discovered very simple hack. I add the following string to my module initialization function: PyInt_Type.tp_as_number->nb_divide = gen_div; Here gen_div is the function I use for division of objects of my new type. This solution is pretty nice since I do not have to make changes into python or interactive shell. It is even better to make a function which would 'turn on/off' my division. It is strange that it is only possible to do such things in C code, I cannot do it from python. Anton -- http://mail.python.org/mailman/listinfo/python-list
