I'm trying to understand the argument flags that are used in the method table of an extension module written in C.
First let me ask this question about the method table. Is it an C array named "PyMethodDef"? Now, onto my questions about the arguments: [1] I see that even when the Python function we are supplying takes no arguments, (the argument flag is METH_NOARGS), that we still pass the C function a reference to "self". Is this "self" actually a pointer to the section of memory that represents the object in Python that is calling the method? [2] What is the difference between "positional" arguments indicated by the METH_VARARGS argument flag, and "keyword" arguments that are indicated by the METH_KEYWORDS argument flag? Does one determine the identity of an argument based on the order or position in which the arguments are passed to the C function, while the other uses keys in a dictionary to identify the arguments? That should be the start of my customization questions... :] If it is any consolation I hope to take what I learn and put together a tutorial on expanding Python for those that only have a little experience with C programming, like myself. I plan to explain everything like I was teaching a 6-year old. :] I was just going to put this on a wiki, but is there a way to include with other Python documentation on an "official" site? Thanks for the help. Scott Huey -- http://mail.python.org/mailman/listinfo/python-list
