Write a program in python to test if given number is prime or not.

def main():

num = int(input("Input a number to check for prime: "))

if num > 1:

 for i in range(2,num):

 if (num % i) == 0:

   print("%d is not a prime number" % num)

   break

 else:

   print("%d is a prime number" % num)

   break

else:

 print("%d is not a prime number" % num)

if __name__ == "__main__":

main()

Explanation:

Solution retrieved from programiz.com.

Note, this program uses the idea of the Sieve of Eratosthenes to validate the input number by using the modulo operator to determine primeness.

The program will output to the user if the number input is indeed prime or not.

Cheers.

Explanation:

num = int(input("Enter a number to test if it's prime or not: "))

if num%2 == 0:

   if num == 2:

       print(num,"is prime")

   else:

       print(num,"is not prime")

else:

   count = 0

   for x in range(2,num):

       if num % x == 0:

           count+=1

   if count==0:

       print(num,"is prime")

   else:

       print(num,"is not prime")

I wrote my code in python 3.8. I hope this helps!

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.
