Show HN: Python.cards – Learn Python with spaced repetition

Hi HN! During the last year, I've been building python.cards: a site to learn Python using spaced repetition.

My goal is to make the most of spaced repetition by making it extremely simple to use and by providing high quality flash cards.

The site has been live for a month, with a few daily users who had joined the waitlist. The feedback has been quite positive, with most of the users using the site every day.

Currently, we have a free deck (A Tour of the Stdlib) and a paid one (Pathlib in depth, for $9.99). I have other decks in the works, covering topics such as f-strings, collections, nomenclature, built-ins, exceptions and more. Your feedback is very welcome for me to prioritize which decks to build first.

In my way to launch, I've open sourced simple-spaced-repetition, a Python module that implements the classic Anki algorithm (https://github.com/vlopezferrando/simple-spaced-repetition/), and I released some videos live-coding the site and building the decks (https://www.youtube.com/channel/UCyWUj9r0soytotuuh2JnPrw).
