# Python Math: Find the next previous palindrome of a specified number

## Python Math: Exercise-23 with Solution

Write a python program to find the next previous palindrome of a specified number.

A palindromic number or numeral palindrome is a number that remains the same when its digits are reversed. Like 15951, for example, it is "symmetrical". The term palindromic is derived from palindrome, which refers to a word (such as " REDIVIDER" or even "LIVE EVIL") whose spelling is unchanged when its letters are reversed.

**Sample Solution**:-

**Python Code:**

```
def Previous_Palindrome(num):
for x in range(num-1,0,-1):
if str(x) == str(x)[::-1]:
return x
print(Previous_Palindrome(99));
print(Previous_Palindrome(1221));
```

Sample Output:

88 1111
