<p class=MsoNormal>I need to call Python function from C# to get a value.
When I call the script it executes and calculates some value, then I need
to call some function to get the result. How do I do that? I have the following
snippet of code that seems to execute the script, but I don't know and can't
find on line, how to call a function and get value back.<o:p></o:p></p>
