In this program, you’ll learn to find the sum of natural numbers using recursive function.
To understand this example, you should have the knowledge of the following Python programming topics:
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.
