XBox button debouncing

edit

Hey,

I want to implement button debouncing for my xbox controller and I couldn't find anything much helpful till now. All the info that is available on google is related to microcontrollers. Is there an option or a way button debouncing can be implemented in a ros python code?

Thanks in advance

Edit:

@PeteBlackerThe3rd In the pic you can see that the joint changed once, when I gave the input through the controller, but instead of stopping at the first 'Plan complete', the loop ran for 7 more times, which causes a bit of delay in processing the second instruction given through the controller. Could you maybe point out my mistake or maybe guide me through the right process so that I can detect my mistake?

Edit-2 Code screenshot: I know it's not suggested to take a screen shot of the code and post it here, but I just wanted to make sure that the indentations I am having in my code are clear, since indentations are a not always correct here

Edit -2

This is my code

    global a, flag1, flag2, j1
    if ((data.buttons[0]==1) and (data.axes[6]==1)):
        if (flag1 == 0):
            a += 1
            flag1 = 1
            j1 = (int(a))*0.1
            print "Value of Joint 1 is: %s " %j1
            if (j1 >= 3.1): 
                group1_variable_values[0] = 3.1
                print "Limit reached joint 1"
            else:
                print "changing joint 1"
                print "Plan completed"
        group1_variable_values[0] = j1
        group1.set_joint_value_target(group1_variable_values)
        plan2 = group1.plan()
        execute2= group1.execute(plan2)
        rospy.sleep(1)
        print "plan complete"
    else:
        flag1 = 0

    robot = moveit_commander.RobotCommander()
    group1 = moveit_commander.MoveGroupCommander("igus_planning")
    group1_variable_values = group1.get_current_joint_values()
