Dear Steven,

Thank you for your kind suggestion. 
I will keep it in mind.

I am trying to send you a revised example.
list1=[u"('koteeswaram/BHPERSN engaged/NA ','class1')", u"('koteeswaram/BHPERSN is/NA ','class1')"] 

[('koteeswaram/BHPERSN engaged/NA ','class1'),
 ('koteeswaram/BHPERSN is/NA  ','class1')]

I tried to make it as follows,
list2=[]
for i in list1:
        a1=unicodedata.normalize('NFKD', i).encode('ascii','ignore')
        a2=a1.replace('"',"")
        list2.append(a2)

and,

for i in list1:
        a3=i[1:-1]
        list2.append(a3)


but I am not getting desired output. 
If any one may kindly suggest how may I approach it? 

Regards,
Subhabrata
