Find Factorial of Number in Python Using Recursion

Python Program to Find Factorial of Numbers Using Recursion

# Find Factorial of Number in Python Using Recursion
def recur_factorial(n):
   if n == 1:
   	return n
   else:
   	return n*recur_factorial(n-1)

# we are taking a number from user as input
# entered value will be converted to int from string
num = int(input("Enter a number: "))

# check if the number is negative
if num < 0:
   print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
   print("The factorial of 0 is 1")
else:
	# number is passed to the recur_factorial() function
   print("The factorial of", num, "is", recur_factorial(num))

Output:

Enter a number: 5
The factorial of 5 is 120
