Python Code to Find Sum of Natural Numbers Using Recursion
In this program, you’ll learn to find the sum of natural numbers using recursive function.
In the program below, we’ve used a recursive function recur_sum() to compute the sum up to the given number.
Source Code
# Python program to find the sum of natural using recursive function
def recur_sum(n):
if n <= 1:
return n
else:
return n + recur_sum(n-1)
# change this value for a different result
num = 16
if num < 0:
print("Enter a positive number")
else:
print("The sum is",recur_sum(num))
Output
The sum is 136
Note: To test the program for another number, change the value of num.
