Question vizjoy.py Twist method

Going over some old code and I had a question.

Years ago, I modified vizjoy.py for the twist method.
The original method is:

Code:
def getTwist(self):
	"""Returns the twist of the joystick"""
	return self.getRotation()[2]
My new method hardly changed anything:

Code:
def getTwist(self):
	"""Returns the twist of the joystick"""
	return self.getRotation()
Why do you only return the second element of the joystick? For other hardware such as the XBoxController with 2 sticks, I can't directly query the state without this information or utilize the overwritten callback to twist that is in your documentation.

That is, I wouldn't be able to do the following with only one element being passed from getTwist

Code:
def twist(self, val):
	self.xRAccel = 0.0
	self.yRAccel = 0.0
		
	if (abs(val.twist[0]) >= self.deadZone):
		self.xRAccel = val.twist[0]

	if (abs(val.twist[1]) >= self.deadZone):
		self.yRAccel = val.twist[1]
Is there something I am missing? Is there another method someplace to get this information about the second analog stick?

If you want all rotation values, then simply call joy.getRotation() instead of joy.getTwist(). As shown in the code you posted, getTwist is simply a convenience method to get the Z-rotation value of the joystick. There is no need to modify vizjoy.
