If you’ve been using Python for years and know enough to get the job done, it’s probably not a wise use of your time to read through several thousand pages of documentation just to maybe discover a handful of new tricks. So I’ve put together a short (by comparison) list of features that aren’t widely used, but are widely applicable to general programming tasks.
This list will of course contain some stuff you already know and have a sprinkling of things you’ll never use, but among them, I hope there are a few that are new and useful to you.
