How to check whether a given number is a twisted prime number in Python

Answer 1

import math 

def reverseNumber(n) :
    reverse = 0
        
    while (n != 0):
        reminder = n % 10
        reverse = reverse * 10 + reminder
        n = int(n / 10)
      
    return reverse
    

def isPrime(n) :
    if (n < 2 or (n % 2 == 0 and n != 2)) :
        return false
    
    count = int(math.floor(math.sqrt(n)))
    for i in range(3, count, 2) :
        if (n % i == 0) :
            return False
    return True


n = 79
reverse_n = reverseNumber(n)
    
if (isPrime(n) and isPrime(reverse_n)) :
    print("Twisted prime number")
else :
    print("Not twisted prime number")
