Solution 1:

Tkinter widgets and canvas items are just thin wrappers around objects that exist in an embedded tcl interpreter. You can't use deepcopy or pickle to create multiple instances because those commands know nothing about the embedded tcl interpreter. If you need multiple instances, you must call the appropriate tkinter functions.
