Python help

10- Write a Python program to add the digits of a positive integer repeatedly until the result has a single digit. For example, for a number like 58, it would be 4 since: 5+8-13 1+3-4 Guidance: a simple and straightforward solution is to check if the number n is bigger than oor sum>9. Assuming one of them is right (that the condition evaluates to True) you get to the loop since you need to repeat this check manytimes then while0 loop is the right choice, not the "if", you get the right digit by getting the remainder by 10 of the number: >>> 309%10 Save the result in a variable called "sum" and then drop the rightest digit by integer dividing to 83: >>309//10 30 Repeat this process until both N
