How to execute code "synchronously" or know when script is done?

[RaelB 1]

The GUI examples work fine for demonstration purposes, but how do I use the components to execute python code and get a result within my own code, i.e synchronous execution, or be notified when execution is done?

e.g:

S := PythonExec(input_script)

 

Then I can use S in next line of code, or in an event that notifies script is done.

Thanks

By bad, it looks like the code does in fact execute synchronously..
