I can't help with threading.timer since I've never used it but...

Use int() or float() ?

Possibly. If you are using wxPython there is a timer (wx.Timer) in there 
that will fire an event (EVT_TIMER) after a suitable delay. This moves 
the timed event into your main processing code rather than having it in 
a thread. That might be easier. You can certainly start/stop the timer. 
You can recreate the timer with a new value after stopping. You can 
reuse the same variable name to store the timer.
