[Tkinter] How to erase previous output from the canvas?

[Pedroski55]

Found two solutions in the end, just in case anyone is interested:

1. When an object is created, it's ID is returned, save that:

the_id = canvas1.create_window(200, 250, window=label4)

then:

canvas1.delete(the_id)

If you use this in a callback to a function, you need to declare it global:

global the_id

2. Use a tag:

canvas1.create_window(200, 250, window=label4, tags="label")

then:

canvas1.delete("label")

More than 1 object may have the same label, so that allows you to do things to all objects with that tag.
