Dear Group,

Thank you for your kind time and reply. True as Steven pointed the error should be specific. I tested. Put comment mark before the set assignment, printed the list as Peter suggested, taken the print of the list, but no it is not my problem, as you suggested what is contained in the list, I am taking out the values and then assigning blank list and appending the processed values in the list. 
If this kind of problems happen, --rare but in my 6 yrs Python experience happened sometimes--then I take a new window, rewrite or copy the earlier code module by module, give a new method name--believe it or not--- works. 

Regards,
Subhabrata.
