Ask HN: What are the best tutorial for learning Flask?

Grinberg's tutorial is pretty good. The book version is "Flask Web Development" (O'Reilly). There are some bits of it that are out of date. You can use my "flaskula" repo as a reference with some fixes: https://github.com/joeclark-phd/flaskula

The first one whets the appetite with an overview/setup and the second one gets your hands dirty building a CRUD app.

The tutorials/examples on the site itself are best introductory stuff I've used.
