Yes, indeed I did, thanks. Apart from using augmented assignment,
that's exactly what I would have put there, if I'd actually taken a
moment to test the code.

Right again. Fortunately, Py3 would catch that one with a TypeError.
See? This is why you should use Py3. :)

No no, nitpicking is exactly what ensures that the end result is
correct. If I got offended at you correcting my code, it would imply
that I think myself perfect (or at least, that I consider you to be
utterly incapable of noticing my errors), which is provably false :)
One of the mind-set changes that I had to introduce at work was that
people don't own code, the repository does - if you see an improvement
to something I wrote, or I see an improvement to something you wrote,
they're improvements to be committed, not turf wars to be battled
over.

Especially on something like this, please *do* catch other people's mistakes :)
