Can you give me a code based on the given skeleton code?

[Bhavika]

I am given a problem for digit powers from project Euler problem 30 where I have to write code using oops.
The skeleton code is:

class digitpower():
    def __init__(self):
    #add code here
    def isarmstring(self,number):
    #add code here
    def sumofarmstrongnumbers(self,start,end):
    #add code here
