The code is working as I want it to but the last message and the original

As others have pointed out, a mapping/dictionary or just a list of lists
seems like how you would want to organize the data for input. I think your
problem is insistence on using sets. I am no Python guru, but I think this

err, set also is unordered. I can see you are using set for a reason, but
has no concept of order.

Just glancing at your work, I see you have curly braces around what looks

Hi,
The reason I opened a link is because there are changes in the code. Does
it make sense? Else I can definitely go back to the thread.

Hi Raj,
It might be easier if you create a simple test string inside the
python interpreter and then tinker with it there. once you've found
the solution, you can graft it onto the broader program that accepts
