Python: How to properly delete timer created using wx.Timer

Question

In Python, using wxPython Phoenix 4.1.1, I have created a timer using the wx.Timer object like below. Later, at some point in the code, I want to delete the timer after I have stopped it from running. Please, what is the most clean and proper way to delete the timer?

The timer creation code is following. The self variable refers to a wx.Dialog object.

self.timerId = 1
self.timer = wx.Timer(self, self.timerId)
self.Bind(wx.EVT_TIMER, self.onTimer, self.timer)
self.timer.Start(10)

The timer deletion code I have so far is this:

self.timer.stop()
# Probably an 'unbind' method should be used here, but what is the exact syntax?

Thanks.
