A very simple Palindrome checker

print "What is the word you would like to check?" # Asks the user what word they would like to check.
x = raw_input("> ") # User inputs the word.
y = x[::-1] # reverses the string.
if x.lower() == y.lower(): # checks if the strings match, this way it handles case sensitivity.
    print x,"is a palindrome!" # prints it is a palindrome
else: # and if it's not a palindrome
    print x,"is not a palindrome!" # it will print it is not a palindrome!
