run different functions each time the same button is pressed?

[User3000]

I am using python inputs library to detect gamepad button presses.

Purpose: I want to change the listening mode of my Pioneer AV-Receiver when pressing RB on my Xbox Controller. The event is logged as 'BTN_TR' through python inputs library.

Right now when I press the button it loops through all added listening modes when I press RB once. (as expected) but that's not what I want. I want to change from one listening mode to the next each time I press RB.

So when I press RB for the first time it should switch from Auto Surround to Rock/Pop. When I press RB again it should switch to Ext.Stereo. And the third time I press RB it should switch back to Auto Surround.

This is my code right now. What do I need to change?

def main():
	while 1:
		events = get_gamepad()
		for event in events:

			lmd_query = eiscp.eISCP('192.168.0.59').raw('LMDQSTN')

			if lmd_query == 'LMD80': #autosurround 
				if event.code == 'BTN_TR':  
					eiscp.eISCP('192.168.0.59').raw('LMD06') #rockpop  
   
			if lmd_query == 'LMD06':  
				if event.code == 'BTN_TR':
					eiscp.eISCP('192.168.0.59').raw('LMD0C') #ext.stereo

			if lmd_query == 'LMD0C':  
				if event.code == 'BTN_TR':
					eiscp.eISCP('192.168.0.59').raw('LMD80')
				
if __name__ == "__main__":
	main()

Thank you for reading and if you have an idea please let me know!
