Python reverse() for palindromes

Try y = x[::-1]. This uses splicing to get the reverse of the string.

reversed(x) returns an iterator for looping over the characters in the string in reverse order, not a string you can directly compare to x.

reversed returns an iterator, which you can make into a string using the join method:

y = ''.join(reversed(x))

For future reference, a lambda from the answers above for quick palindrome check:

isPali = lambda num: str(num) == str(num)[::-1]

example use:

isPali(9009) #returns True
