      if number % i == 0:
         return False
         return True
if __name__ == '__main__':
   number = 17377
   start_time = time.perf_counter()
   is_prime(number)
   end_time = time.perf_counter()
# printing the executing time by difference
print(end_time - start_time)

Output

If you execute the above program, then you will get the following result.
