Q: Help in to Write a Python class definition for class Sumi with a single instance variable self.num of type int and single instance method called sum_of_digits. The default constructor sets the instance variable equal to zero. The instance method returns the sum of digits of the instance.Please note that I do not know the number of digits in advance. This class has to have a RECURSIVE (to call itself):

Given is the Information to make this Python class:

>>> n = Sumi(369)

>>> sum_of_digits(n)

18 >>> m = Sumi() >>> sum_of_digits(m) 0 Hint: use the binary operators // and %. Each method of a class has to have self as a first parameter, i.e. do this: def recur(self, num). Make sure you use self, when you call the method recursively. Remember: The Three Rules of Recursion Base (termination) condition Decomposition to smaller instance Use solutions to smaller instances to solve the original problem
