[issue31309] Tkinter root window does not close if used with matplotlib.pyplot

[Terry J. Reedy]

Terry J. Reedy added the comment:

This is purely a tkinter issue.  Windows people can ignore this.

Your problem was a result of your program error, of not keeping a reference to Tk(), combined with tkinter's _default_root 'feature'.

The solution you report in your answer, 'root = tkinter.Tk()', later followed by an explicit 'root.destroy()' is *the* correct way to do what you want.  I explained further in my answer.

There is no way for askopenfilename to know that you are done with root or tkinter._default_root.
