Extending Embedded Python and execute external script

[Vertilka]

What i need from my C application to do ?
1) To execute a python script from file.
2) The python script will call functions in my C application.

According to the answer from Ravi Teja (topic "C app and Python"), I
need to extend embedded python in my C application.

I saw several functions: PyRun_AnyFileExFlags, PyRun_SimpleFileExFlags,
PyRun_FileExFlags.

Questions:
1) Which one should i use in order to achieve what i need ?
2) I couldn't understand the differance betwwen the three ?
3) What is the difference between the "FILE *fp" and "const char
*filename" arguments of these functions. If i give a FILE*, why do i
need to give the file name ?

Tnx,
Vertilka

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.

3) What is the difference between the "FILE *fp" and "const char
*filename" arguments of these functions. If i give a FILE*, why do i
need to give the file name ?

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