Welcome folks today in this post we will be finding factorial of number using recursion method in python. All the full source code of the application is given below.

Get Started

In order to get started you need to make an app.py file and copy paste the following code

app.py

# Factorial of a number using recursion

def recur_factorial(n):
   if n == 1:
       return n
   else:
       return n*recur_factorial(n-1)
   
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:
   print("The factorial of", num, "is", recur_factorial(num))

Now if you execute the python script by typing the below command

python app.py
