Given an integer x, return true if x is a palindrome__, and false otherwise.

Example 1:

Input: x = 121
Output: true
Explanation: 121 reads as 121 from left to right and from right to left.

Example 2:

Input: x = -121
Output: false
Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.

Example 3:

Input: x = 10
Output: false
Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Constraints:

  • -231 <= x <= 231 - 1

My Answer

class Solution:
    def isPalindrome(self, x: int) -> bool:
        value = str(x)
        length = len(value)
        for i,item in enumerate(value):
            if item != value[length-i-1]:
                return False
        return True
