That was not tkinter behavior. And it was not the behavior in 2.x.
The above only worked (in 3.x) when running from IDLE, as an undesirable
side-effect of imports made by IDLE's run.py before running user code.
It did not work when running with Python directly, and should not have
according to the language definition. It was a bug in IDLE that I fixed
for 3.5.3 (just checked), and 3.6.0. See
https://bugs.python.org/issue25507
for an explanation.

or
from tkinter import messagebox
messagebox.showerror(...)
or even
from tkinter.messagebox import showerror
showerror(...)
