This should be linear complexity and short circuiting a

Yes, there's something beautiful about writing "first = next" :-)

This should be linear complexity and short circuiting and in general it
doesn't get much better than this. Though I wouldn't bet there isn't a
better (faster/clearer/more readable) solution.

Neither Python nor Tkinter include interface libraries to talk to hardware
printers out of the box, but a number of libraries and methods exist
depending on your platform. Both Wx and Qt, UI toolkits with great Python
bindings, do support printers to one degree or another, although I don't
know how

Any recommendations on normalizing path strings in cross platform
(Windows, Linux, macOS) for unit tests?
Our goal is to normalize path strings to use forward slash separators so
that we can consistently reference path strings in our unit tests in a
cross platform way.

I need to select a Python GUI. It needs to cover all of the desktops
(Linux, Windows, Apple) and hopefully mobile (Android and Ios). I'm
looking at Kivy, but have yet to find an example app. that has a native
