Simple Tkinter problem

Here's my Tkinter class:

class TwoChoice:
    def __init__(self, master):

        frame = Frame(master)
        m = Label(root, text= maentry)
        n = Label(root, text= fave)

        self.button = Button(frame, text=home_team, command=

        self.hi_there = Button(frame, text=vis_team,

    def comm_1(self):
        print home_team

    def comm_2(self):
        print vis_team

I call it by

root = Tk()
gui= TwoChoice(root)

The next time I call it I want to just run the same thing but with
different values for the variables. Instead it gives me like two copies
of the widget.
