Products that do what I wrote a book on idiomatic Python. Here's its insane build/test system does

Background: I've been working on a book to help developers learn and write idiomatic Python. It's taken far longer than I imagined, but today I made it available for purchase (http://www.jeffknupp.com/writing-idiomatic-python-ebook). The automated build and test system I'm using is ridiculous. It uses: virtualenv, tox, pytest, coverage, doctest, pandoc, make, xelatex, makeindex, and a ~200 line Python script to collect and format the output. The details of the build/test system I created are described in detail here:…

    My book titled "Python re(gex)?" is free to download through this weekend [1][2] The book covers both 're' and 'regex' modules, has plenty of examples and chapters also have cheatsheets and exercises. Code snippets, exercises, sample chapters, etc are available on GitHub repo [3] I used pandoc+xelatex [4] to generate the pdf.

    Hi everyone! I just released the Practical Python Projects book! (https://practicalpython.yasoob.me) I am happy to announce the first version as a release candidate. I have poured a lot of love into writing this book and would love to hear what you guys think. (A limited 100% off and discount coupons at the end) This is not a pure beginner book. The book does assume some background Python knowledge. You need to know the basics like methods, functions, classes, and such. If I use something that is not typically covered in beginner Python books, I will explain it before I use it.…

    Hi HN, Over the past 6 months I've been working on a technical book focused on helping aspiring data scientists to get hands-on experience with cloud computing environments using the Python ecosystem. The book is targeted at readers already familiar with libraries such as Pandas and scikit-learn that are looking to build out a portfolio of applied projects. To author the book, I used the Leanpub platform to provide drafts of the text as I completed each chapter. To typeset the book, I used the R bookdown package by Yihui Xie to translate my markdown into a PDF format. I also used Google docs…

    Hey HN. I've just launched my very first webappp and would love your feedback. http://www.7bks.com It's a book list sharing website - kind of like playlists for bookworms. The site is built on pyton/appengine - and I learned to code in under 4 weeks to build the site. There's more details on the background of the site here: http://www.7bks.com/blog/179001 I've also published the full Python code for the site here: https://gist.github.com/670034 Feedback is really important to me and I want to work hard to make the site better so any and all suggestions are greatly appreciated. Contact…

    This is a little project I've been working on for a while in order to better learn Python. Although IRC may not exactly be the most exciting medium, I still find it to be fun and useful, this interest lead me to writing a bot. In doing this I realized that what would actually be more interesting would be if I had a framework. There may already be such a thing, certainly there are IRC libraries, but I don't know if they're well-suited to deploying bots. At any rate if for no other reason than the fact that I am relatively new to programming and eager to learn I decided to build a framework.…

    Read an article about analyzing Garmin data with AI. Sounded great — except I didn't want to send my health data to any cloud service. So I asked Claude to write me 2-3 scripts and a dashboard. This escalated a bit. 30 days and 20$ later I have this: A local-first Garmin archive with interactive HTML dashboards, Excel exports, weather and pollen context, AES-256 encrypted token storage, and a self-healing data pipeline with 515 automated tests. Windows desktop app, no terminal needed. Nothing leaves your machine. I never wrote a line of Python. I understood the problems and made the…

    I've made another Python cheat sheet tutorial. Yeah yeah, nothing new, I know. But here's the thing: The main idea was not just to write a wall of text telling about everything, but to make it interactive. So that everything would have its own example code snippet, which you could change, run, and see how it worked. And not somewhere in a web version, but on your own computer, in your own environment. Fortunately, Python has the perfect tool for this - the Jupyter Notebook. That's why all chapters are written as separate notebooks and there is an example for each point (well, almost). I…

    Hello everyone! After two years of hard work, I'm excited to announce the release of my first book, "From PHP to Python". As developers, it can be frustrating to learn a new language from scratch. This is why I wrote this book to help PHP developers quickly learn Python by focusing on what's different and taking shortcuts when things are similar. It's written in a straight-to-the-point style and the chapters are concise and condensed. The book covers everything needed in my opinion to have solid foundations in Python, in a web-oriented approach. After finishing this book, you will be able to…

    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,…

    cataclysm is an over-the-top experiment to take more of the human out of coding. Any function you give it, it generates and executes. No need to think about what you need, it'll make it for you. I haven't taught it to use itself yet if a module isn't installed, but that's next on the agenda once GPT4 isn't so slow. Video intro here: https://www.youtube.com/watch?v=ZK8fUuQDgZ4 Some random examples when using global cataclysm: >>> uhoh = first_prime_with_3_digits() >>> print(uhoh) 101 >>> scary_words = get_italicized_phrases_wikipedia(page="Global catastrophic risk",…

    @cmpyl Tweet a line of python at it (right now it works best with math) and it'll tweet back at you the return value. Ex: https://twitter.com/#!/cmpyl/status/186850674053615616 Pretty useless little bot but it will be cool to see what sort of wild one liners it finds.
