def recursiveDigitSum (n):

if n<10:

return n

else:

return (n%10) + recursiveDigitSum (n/10)

print (recursiveDigitSum (93))

Explanation:

Inside the recursiveDigitSum function, use an if condition to check whether the given number is less than 10. If it's true, return the number as this will act as a stopping criteria. Otherwise, keep on calling the recursiveDigitSum function recursively. Lastly call the recursiveDigitSum function.
