launch python file programmatical

Hello everyone,

I am currently building an eclipse plugin where I wish to keep multiple python files in a hierarchical structure, i.e. grouped in folders.
Now my concern is how to launch them. I could launch each file manually and give the file the arguments by hand, but that will be too much work.
I would like to have it in a way that I write a function to read the arguments from a text-file and then launch each .py-file in a specified folder programmatical. Like this:

launch(IFile pyFile, String args)

I have found an article on how to launch java-programs (http://www.eclipse.org/articles/Article-Java-launch/launching-java.html), where I found this snippet:

ILaunchManager manager = DebugPlugin.getDefault().getLaunchManager();  
ILaunchConfigurationType type = manager.getLaunchConfigurationType(ID_JAVA_APPLICATION);

Now my first question is, which String Constant would I have to use to get the LaunchConfigurationType applicable for python? If you know a better way like reading a *.launch-file from the project folder after manipulating the arguments stored therein, let me know.

Further snippets deal with setting details of the LaunchConfiguration like classpath, I do not think this will be a big problem.

The last thing is actually runnig the python file, which sould go well with

ILaunchConfiguration configuration = workingCopy.doSave();
DebugUITools.launch(configuration, ILaunchManager.RUN_MODE);

given that the file itself is stored in the configuration.
And here is my second question: Does this approach make sense or do you know of any detail I missed?

Any help is greatly appreciated!
