Python program to check number is prime or not using recursive

def prime_or_not(n, div = None):
    if div is None:
        div = n - 1
    while div >= 2:
        if n % div == 0:
            print("Given number is not prime")
            return False
        else:
            return prime_or_not(n, div-1)
    else:
        print("Given number is prime")
        return 'True'
num=int(input("Please enter a number: "))
prime_or_not(num)

      Output 1:
             Please enter a number: 7
             Given number is prime
      Output 2:
             Please enter a number: 18
             Given number is not prime
