Execute python script via C API line-by-line

[Oliver Eichler]

Hi

Is it possible to execute a Python script via C API interactively? Like: 

- read the file
- execute 1st line 
- tell next/current line (especially usefull for loops and function calls)
- execute next line
- ...

As far as I can see from the documentation I can use the normal commandline 
interface or execute a file as one single call. There seems to be some 
parsing functionality described, however, the official API documentaion is 
too brief to make much sense to start with. Is there a better C API docu to 
start with (books/link)? Something explaining the concepts in detail?  


Just as background:
I would like to control some hardware via python script for testing 
purposes. That's why I would like to step thru the script line-by-line. The 
aim is to have a text edit widget with the script code and the current line 
to process highlighted.

Thanks for hints, details and stuff

Oliver
