Why don't you try by yourself? You can use: print repr(something)

So you answered your first question yourself: event.widget is the canvas,
not the bitmap.
On another thread you get the other answer.

and what can i do with this number anyway?

With that specific number, nothing. The whole text says two things:

- *what* the object is: a Tkinter.Canvas instance
- *which* one: this is not the same one as <Tkinter.Canv as instance at
0x12345678>

If your image is a canvas item (i.e. created with canvas create_image
method), then you can use
the method tag_bind to handle events specific of that item.
In that case, the callback argument is a Tkinter.Event instance.
