Below the code will print 0 if it is Palindrome else it will print -1
Optimized Code
word = "nepalapen"
is_palindrome = word.find(word[::-1])
print is_palindrome
Output:
0
word = "nepalapend"
is_palindrome = word.find(word[::-1])
print is_palindrome
Output:
-1
Explaination:
when searching the string the value that is returned is the value of the location that the string starts at.
So when you do word.find(word[::-1]) it finds nepalapen at location 0 and [::-1] reverses nepalapen and it still is nepalapen at location 0 so 0 is returned.
Now when we search for nepalapend and then reverse nepalapend to dnepalapen it renders a FALSE statement nepalapend was reversed to dnepalapen causing the search to fail to find nepalapend resulting in a value of -1 which indicates string not found.
Another method print true if palindrome else print false
word = "nepalapen"
print(word[::-1]==word[::1])
output:
TRUE
