Using values from a list of tuples within a loop

[jtpy]

Hello buran, and thanks for your message.

I have stripped down the code a bit to post it here and have used the print function just to make it easier for people to see what's happening. The actual script simply writes the function's output to a file.
I'm aware that other things could be improved but this is a work in progress anyway.

But anyway, do you have an idea about how to achieve what I explained initially? Would really appreciate any help.

Best regards,

jtpy
