Question

For Python:

A prime number is defined as an integer greater than 1 that has no positive divisors other than 1 and itself. Write a program that prompts the user for an integer > 1. Validate the value is > 1 (if not, ask for another). Use a loop to determine if the number is prime or not. Issue an appropriate message. [complete this part before proceeding]. Add a loop that continues to ask the user if they would like to enter more numbers to test.

Answer 1

n = int(input("Enter a positive integer: "))

is_prime = n > 1
for i in range(2, n):
    if n % i == 0:
        is_prime = False

if is_prime:
    print(n, "is a prime number")
else:
    print(n, "is not a prime number")

Answer 2

n = int(input())

if (n>1):

flag = False

for i in range (2, n):

if (n % i) == 0:

flag = True

break

if flag == True:

print('NOT PRIME')

else:

print('PRIME')

else :

print('NOT PRIME')
