PyRun_SimpleFile or PyRun_SimpleString should be good enough.  Using
SimpleString is more robust:

and also lets you implement additional glue in Python code instead of in C/C++.

AnyFile supports interactive devices, RunFile requires you to provide a custom
execution context.

Python needs the filename to be able to give meaningful error messages.
