When you use optional named arguments in a function, how do you deal with with
the incorrect assignment when only some args are supplied?
If I do something like:

then handle the test cases with:
if not kwargs.get('some_key'):
raise SyntaxError

Dear list,
I am writing a Python extension module that needs a way to expose pieces
of a big C array to python. Currently, I am using NumPy like the following:
PyObject* res = PyArray_FromDimsAndData(1, int*dim, PyArray_DOUBLE,
char*buf);
Users will get a Numeric Array object an
The rpncalc package adds an interactive Reverse Polish Notation (RPN)
interpreter to Python. This interpreter allows the use of Python as
an RPN calculator. You can easily switch between the RPN interpreter
and the standard Python interpreter.

The ratfun module provides classes for defining polynomial and rational
function (ratio of two polynomials) objects. These objects can be used
in arithmetic expressions and evaluated at a particular point.
