n2 = num2 def insert(self): return self.n1 + self.n2 # if we had not prepared self then if would toss an error that n1 and n2 is not really outlined and we have to include self inside the function's perimeter to entry It really is variables
Yeah without paranthesis i wished to produce sry. So the worth of identify you truly get it instead of of self.title for the reason that as far as I'm sure self.name and name are 2 diverse variable. Many thanks
