all palindrome substring python code example

Example 1: string palindrome in python

n = input("Enter the word and see if it is palindrome: ") #check palindrome
if n == n[::-1]:
    print("This word is palindrome")
else:
    print("This word is not palindrome")

Example 2: longest palindromic substring python

class Solution(object):
   def longestPalindrome(self, s):
      dp = [[False for i in range(len(s))] for i in range(len(s))]
      for i in range(len(s)):
         dp[i][i] = True
      max_length = 1
      start = 0
      for l in range(2,len(s)+1):
         for i in range(len(s)-l+1):
            end = i+l
            if l==2:
               if s[i] == s[end-1]:
                  dp[i][end-1]=True
                  max_length = l
                  start = i
            else:
               if s[i] == s[end-1] and dp[i+1][end-2]:
                  dp[i][end-1]=True
                  max_length = l
                  start = i
      return s[start:start+max_length]
ob1 = Solution()
print(ob1.longestPalindrome("ABBABBC"))
