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.
