Later, when it is time to call the function, you call the C function
\cfunction{PyEval_CallObject()}. This function has two arguments, both
pointers to arbitrary Python objects: the Python function, and the
argument list. The argument list must always be a tuple object, whose
length is the number of arguments. To call the Python function with
no arguments, pass an empty tuple; to call it with one argument, pass
a singleton tuple. \cfunction{Py_BuildValue()} returns a tuple when its
format string consists of zero or more format codes between
parentheses. For example:
\cfunction{PyEval_CallObject()}.\ttindex{PyEval_CallObject()} This
function has two arguments, both pointers to arbitrary Python objects:
the Python function, and the argument list. The argument list must
always be a tuple object, whose length is the number of arguments. To
call the Python function with no arguments, pass an empty tuple; to
call it with one argument, pass a singleton tuple.
\cfunction{Py_BuildValue()} returns a tuple when its format string
