Finding Factorial of a given number using recursion.

def recur_factorial(n):  #user-defined function
   if n == 1:
       return n
   else:
       return n*recur_factorial(n-1)
# take input
num = int(input("Enter number: "))
# check number is positive, negative, or zero
if num < 0:
   print('Factorial does not exist for negative numbers')
elif num == 0:
   print('The factorial of 0 is 1')
else:
    # calling function
    print('The factorial of',num,'is', recur_factorial(num))
