Slip 24 Q 1

CODE :

class factorial():

    def __init__(self,num):

        self.num=num

        factnum=1

        if self.num<0:

            print("Sorry, factorial does not exist for negative numbers")

        elif self.num==0:

            print("The factorial of 0 is 1")

        else:

            for i in range(1,num+1):

                factnum=factnum*i

            print('The factorial of {} is {} factorial'.format(num,factnum))

num = int(input("Enter a number: "))

if num > 1:

    for i in range(2,num):

        if (num % i) == 0:

            print(num,"is not a prime number")

            print(i,"times",num//i,"is",num)

            break

    else:

        print(num,"is a prime number")

else:

   print(num,"is not a prime number")

factorial(num)
