The :c:func:`Py_SetProgramName` function should be called before

:c:func:`Py_Initialize` to inform the interpreter about paths to Python run-time

libraries. Next, the Python interpreter is initialized with

:c:func:`Py_Initialize`, followed by the execution of a hard-coded Python script

that prints the date and time. Afterwards, the :c:func:`Py_Finalize` call shuts

the interpreter down, followed by the end of the program. In a real program,

you may want to get the Python script from another source, perhaps a text-editor

routine, a file, or a database. Getting the Python code from a file can better

be done by using the :c:func:`PyRun_SimpleFile` function, which saves you the

trouble of allocating memory space and loading the file contents.
