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

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
