num = int(input(" Enter a number : ")) # define a flag variable flag = False if num > 1: for i in range(2, num): if (num % i) == 0: # if factor is found, set flag to True flag = True # break out of loop break # check if flag is True if flag: print(num, "is not a prime number") else: print(num, "is a prime number")
