--single-quoted-strings would be a really nice option for the vast majority of python programmers that use single quotes by default.
Judging from the additional stars on GitHub, and projects that just migrated (pytest!), I'd say there's a very vocal minority which is very attached to single quotes.
I thought dbl quotes smart for all the reasons in the readme. Me commenting 'this is great' is just noise on HN, and discouraged by the rules. Never take self-selected anything as truth, especially comments (tweets/posts/voluntary votes)
Accuse me of selection bias. Immediately use even more biased selection bias.
