I'd suggest a simpler approach is to use the string/list methods in 
Python:

string1 = list(raw_input("enter a string\n"))  #using a list is easier
string2 = string1[:]  # make a copy
string2.reverse()
if string1 == string2:
     print "The entered string is a PALINDROME"
else:
     print "The entered string is not a PALINDROME"

HTH,
