Sincere Apologies - My Bad 
As the data in my head was transposed to the way this works along with the no headings, I was lost!
I was meaning the Type of Parameter
So changed it in the other row
Error is this now…
What am I missing or doing wrong?
Many Thanks once again @Kulkul
Sorry - Had missed to connect the first Input
Drops that value in the other list now…
Correct error is this
Thanks a lot @Kulkul - U Rock!! 
BTW, what does these Python nodes do extra, that the OTB nodes are unable to do?
I don’t intend to learn Python / go down the route as to how to code… but just curious.
Can you please explain in simple terms so that everyone gets an idea? 
Will update this post in case I find anything more interesting reg the same topic…!
FYI, Python is not a node it is a programming language. It is an advance level of programming.
Below are some links for Python learning resources.

I wish you all the best 
Hi @Kulkul
What I meant by Python Nodes are the Custom Nodes written in Python
I knew that it’s a Programming language and that’s why I had mentioned that I would prefer not to go down the route of learning how to code…!!
Still, Many Thanks for the resources and your Wishes…
@Kulkul
When we are on the Topic - thought I can ask u this also…
Is there any method in the API to access the Tooltip? Intent is to have Tooltip text in another Column in the Excel sheet, so it gets populated along with the parameter. Possible to do this?
@Chandrasekar_Rajaman Could you please create a new topic and ask your query. This topic is already solved.
