Make a button behave differently when pressed a second time (Python)

Question

Say, if I have a button that plays a sound, can I make it so that if you press it a second time it stops the music?

I use Python v.2.7, Easy Eclipse as IDE and wxFormBuilder for the windows.

Here's my code:

import gui
import wx
import wx.media
import pygame
import tkFileDialog

class MainFrame( gui.GUI_MainFrame):
    def __init__( self, parent ): #Definerar KunddatabasMainFrame
        pygame.init()
        gui.GUI_MainFrame.__init__( self, parent ) #Initierar MainFrame f�nstret
        self.sound1=pygame.mixer.Sound('beat1.wav')
        self.sound2=pygame.mixer.Sound('beat2.wav')
        self.recording = False

    def evtBrowse1(self, evt):
        tkFileDialog.askopenfilename()

    def evtSoOne(self, evt):
        self.sound1.play(loops=-1)

Answer 1

I would use a global boolean variable and toggle it each time the button is pressed. The function that is called on the button press would then do different things depending on the state of this variable.

You can of course extend this to an int variable if you want to handle many more cases.
