Does TkInter unbind function prevents the widget on which it is applied from binding further events to the widget ?

Clarification:

Let's say I bound events to a canvas earlier in a prgram:

 canvas.bind("<Button-1>",some_function)

Then at a certain point of the program, we no longer need those events:

 canvas.unbind("<Button-1>")

Can we later do something like this:

 canvas.bind("<Button-1>",OTHER_function)

No, unbinding an event doesn't prevent further bindings on the widget. You can bind an event, unbind it, and then bind it again at a later date as often as you want.
