Pass data through programmable filter
 

I'm very new to Python and this is probably very easy for someone who understands the syntax, so I apologize for my ignorance. I perform a transformation with a programmable filter, but I'd also like to pass all my original data through the filter as well. I can do it variable by variable with the following:

I have 18 scalars I'd like to pass through, and three vectors. Repeating the above code for each one is not ideal. Is there a more elegant way to pass through all my original input data?
