Python Math: Find the next smallest palindrome of a specified number

Python Math: Exercise-22 with Solution

Write a python program to find the next smallest 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:

import sys
def Next_smallest_Palindrome(num):
    numstr = str(num)
    for i in range(num+1,sys.maxsize):
        if str(i) == str(i)[::-1]:
            return i

print(Next_smallest_Palindrome(99));
print(Next_smallest_Palindrome(1221));

Sample Output:

101

Python: Get the Key Whose Value Is Maximal in a Dictionary

>>> model_scores = {'model_a': 100, 'model_z': 198, 'model_t': 150}
>>> # workaround
>>> keys, values = list(model_scores.keys()), list(model_scores.values())
>>> keys[values.index(max(values))]
'model_z'
>>> # one-line
>>> max(model_scores, key=model_scores.get)
'model_z'
