```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```
