In this article, we will solve the assignment of prime number in python using two methods, 1st method is simple and 2nd method is a recursive method.

1. Simple python program to check whether a number is prime or not

number = 29
flag = False
if number > 1:
    for i in range(2, number):
        if (number % i) == 0:
            flag = True
if flag:
    print(number, "is not a prime number")
    print(number, "is a prime number")

2. Recursive python program to check whether a number is prime or not

def check(n, div = None):
    if div is None:
        div = n - 1
    while div >= 2:
        if n % div == 0:
            print("Number not prime")
            return False
            return check(n, div-1)
        print("Number is prime")
        return 'True'
n=int(input("Enter number: "))
