I did in these way but still all my test cases other than 1 getting output wrong answer ,can anyone help me with the solution and what to update in the code ?

!/bin/python3

import math import os import random import re import sys if name == 'main': firstLast = input().split()

first = int(firstLast[0])

last =  int(firstLast[1])

def prime(num):
    if num > 1:
        for j in range(2,num):
            if (num%j)==0:
                return False
                break
        return True
    else:
        return False



f=lambda num:prime(int(num))
count = 0
for num in range(last,first+1): 
    if prime(num):
        if all(list(map(f,list(str(num))))):
            count+=1
print(count)
