I will give upvote! please use python 3 to answer

Digital Root Description Digital Root is to add each digit of a positive integer . If the added value is greater than or equal to 10, then continue to add each digit until its value is less than ten. Completion of a function: digital_root(n), Contains 1 parameter n, which is a non-negative integer Calculate the sum of the digits of n. If the value exceeds one digit, please continue to reduce in this way until a digit is generated . Input No input required The system will automatically bring the value n in Output returnOne digit generated Just return, no print needed Sample Input 1 Sample Output 1 The system will automatically pass in the parameters, you don't need to read the parameters yourself 16 The system will automatically call the function without outputting by yourse if 7 Sample Input 2 0 Sample Output 2 The system will automatically pass in the parameters, you don't need to read the parameters yourself 942 The system will automatically call the function without outputting by yourse it Sample Input 3 Sample Output 3 The system will automatically pass in the parameters, you don't need to read the parameters yourself 132189 The system will automatically call the function without outputting by yourse if 6 Hint example: To test whether you have written correctly in viscode C1 print(digital_root (16) Output is 7 Rule accurate 16 can be changed to the value set by yourself to test
