app = Tk() # creat a tkinter application window called "app"
app.title("TVN Game Show")
app.geometry("300x100+200+100")
b1 = Button(app, text = "Correct!", width = 10, command = play_correct_sound)
b1.pack(side = "left", padx = 10, pady = 10)
In the above code, I understand that "app" is my TK() object. But what is the need and purpose of having it as the first parameter of Button? I feel like I'M asking to many simple questions but my book is doing a rather poor job of explaining all the code.
