9. Palindrome Number

Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward.

Example 1:

Input: 121
Output: true

Example 2:

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

class Solution:
def isPalindrome(self, x: int) -> bool:
x_str = str(x)
x_length = len(x_str)
m_x_length = int(x_length/2)
for i in range(m_x_length):
before = x_str[i:i+1]
after = x_str[(x_length-i-1):(x_length-i)]
if not(before == after):
return False
return True
