Python Program to Find Sum of Digits using Recursion
The below program finds the sum of digits using a recursive approach.
# program to compute sum of digits in number using recursion
# recursive function
def ComputeSum(num):
return 0 if num == 0 else int(num % 10) + ComputeSum(int(num / 10))
# input from user
num = int(input('Enter a number: '))
# function call
print('Sum of digits in number =', ComputeSum(num))Output:
Enter a number: 234
Sum of digits in number = 9
