Really? I'm surprised, I can't think why. > unable to find a module named "__builtin__" or "__builtin__.py" > anywhere in my Python 2.5. Is there one? If there is, where is it? It's C code so it's not a .py file. There is probably a C library/DLL somewhere but the whole point of builtin is that it is built in to the core Python interpreter so there is no physically separate file you can see. You can read the C source here: http://svn.python.org/view/python/trunk/Python/bltinmodule.c?rev=52315&view=markup However you'll find that most of them basically just forward the call to another function elsewhere - sometimes with a bit of input validation first. See the abs() function as a short example: static PyObject * builtin_abs(PyObject *self, PyObject *v) { return PyNumber_Absolute(v); } HTH, Alan G. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
