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.
# 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))
Enter a number: 3
The sum of natural number = 6
