Answer to Question #160224 in Python for alulu

Question

1.   You operate several BurgerStands distributed throughout town. Define a class named BurgerStand that has a member variable for the burger stand's id number and member variable for how many burgers that stand sold that day.

a)           create a constructor that allows user of the class to initialize values for id number and for how many burgers sold that day and a destructor

b)           create a function named justsold that show increments of the number of burgers the stand has sold by one. (This function will invoked each time the stand sells a burger so that you can track the total number of burgers sold by the stand. And returns the number of burgers sold.)

c)           create a function that calculate the total number of burgers sold by all stands.

d)           write in a data file, the list of burger stands and the total number of burgers sold by all stands.

Answer 1

    # initialize values for id number and for how many burgers
    # sold that day

        self.burgersSold=0
    # create a function named justsold that show increments of
    # the number of burgers the stand has sold by one.
    def justsold(self):
        self.burgersSold+=1
        print("The number of burgers for burgerstand with id number "+str(self.idNumber)+" is: "+str(self.burgersSold))
        return self.burgersSold
