Sum of N Natural Numbers using Recursion in Python

The recursion technique can also be used to find the sum of n natural integers. Recursion is a method of defining a function that includes a call to itself. The recursive function allows us to break down a big problem into identical single basic examples that we can easily manage.

Source code:

# Python program to find sum of n natural numbers using recursion

# recursive function
def findSum(num):  
 if(num == 0):
    return num
 else:
    return (num + findSum(num - 1))

# input
num = int(input('Enter a number: '))

# print result
print('The sum of natural number =', findSum(num))

Output:

Enter a number: 3
The sum of natural number = 6
