With that in mind, the PSF has worked to reduce financial exposure and develop a plan to provide content remotely.” (是也乎: 注视之下, 终于还是怂了.. ) 今年将推出新 pip 解析器 PSF BLOG “The developers of pip are in the process of developing a new resolver for pip (as we announced on the PSF blog last year). We aim to roll it out later this year. As part of that work, there will be some major changes to how pip determines what to install, based on package requirements.” 改进 Python 的 Pretty-Printing JAKE EDGE Some changes are being proposed to add more customization to the pprint module in Python 3.10 or later, and while a PEP hasn’t been created yet, there are some internal discussions going on debating whether or not such a change is worthwhile and what the API might look like. The Real Python Podcast 上线 REAL PYTHON podcast A weekly Python podcast hosted by Christopher Bailey with interviews, coding tips, and conversation with guests from the Python community. The show covers a wide range of topics including Python programming best practices, career tips, and related software development topics. (是也乎: 也来了哪… 俺们的也有了哪: fm.101.camp 蟒营™电台 钩陈各种值得探讨 ) Python Scope & the LEGB Rule: 在代码中解析名称 REAL PYTHON In this step-by-step tutorial, you’ll learn what scopes are, how they work, and how to use them effectively to avoid name collisions in your code. Additionally, you’ll learn how to take advantage of a Python scope to write more maintainable and less buggy code. (是也乎: LEGB 法则真的是无上真理, 但是, 官方并没约定一个固定的形式, 所以, 导致大家都在摸索自己的… ) CPython 3.9.0a5 现在可用于测试 PYTHON.ORG DjangoCon Europe 2020 推迟到9月 DJANGOPROJECT.COM 讨论 Discussions ...

For some reason, we are attracted to single-figure summaries of quality, whether it’s lines of code, cyclomatic complexity, or the Pylint score. Personally, I think using these are about as valuable as judging another person based on one of their visible or measurable characteristics.” (是也乎: 对 圈复杂度 们的叕一次私人反击, 但是, 资本将重构一切. ) 用 PyGame 作 2D 卷轴游戏 REAL PYTHON video In this step-by-step course, you’ll learn how to use PyGame. This library allows you to create games and rich multimedia programs in Python. You’ll learn how to draw items on your screen, implement collision detection, handle user input, and much more. (是也乎: 卷轴式游戏从无到有… ) 机器学习十大 Python 软件包 ACTIVESTATE sponsor The field of data science is rapidly growing and relies heavily on Machine Learning; with hundreds of ML libraries, Python has become the language of choice for most engineers. Check out ActiveState’s list of the top 10 ML packages to learn → (是也乎: 一直低调赚钱的 ACTIVESTATE , 发布的 Python 发行版本可以说是最稳定的一支; 他们心目中的 ML 模块是: #10 Matplotlib #9 Natural Language Toolkit (NLTK) #8 Pandas #7 Scikit-learn #6 Seaborn #5 NumPy #4 Keras #3 SciPy #2 Pytorch #1 TensorFlow 嗯哼, 有两个纯粹可视化模块… 以及, TF 完胜 PyTorch … ) ...

2020 应该如何享用 Jupyter? 原文: PyCoder’s Weekly - Issue #411 200311 Zoom.Quiet(大妈) 用时 42 分钟 完成快译 200311 Zoom.Quiet(大妈) 用时 17 分钟 完成格式转抄. Post-Mortem Python 绘图 ANDY JONES Who loves debugging things that only fail occasionally? Just me? Maybe you need to check out Andy Jones’ extract() function that “magically” extracts a caller’s environment into an IPython interpreter session. Mix in a little post-mortem debugging with Jupyter’s %debug magic command, and you’ll be painlessly debugging finicky code in no time. (是也乎: 神奇的事后验尸, extract() 能将调用者环境装配人 Jupyter 进行细致的检验. ) 2020 年如何用 Jupyter 笔记本 LJ MIRANDA In this first of a three-part blog post, LJ Miranda surveys the data science landscape and discusses the forces that push data science tools to evolve. (是也乎: 一个系列, 刚刚发布第一篇, 1: 数据科学的笔记本 /2: 2020我的笔记本 /3: 笔记本的未来.. 是的, 笔记本从实体的, 到电脑形态, 现在又是一种可计算文档的指代了… 其实, 对 Jupyter 的发展是看好的, 但是, 对其最终产品形态不明朗, 因为 notebook 形式非常创意的将 开发/调试/笔记/发行 很好的揉合在一起; 唯独没对运行时有考虑…这就比较尴尬了… ) 思考 psycopg3 DANIELE VARRAZZO A core maintainer of the popular psycopg2 PostgreSQL adapter for Python discusses breaking changes he would like to see in a hypothetical pyscopg3 project, including better query/parameter separation, more sensible context manager behavior with connections, and async support. (是也乎: 当大家大规模从 MySQL 迁移到 Pq , 各种模块就大发展起来了… ) Alexa Python 开发: 构建和部署 Alexa Skill REAL PYTHON In this tutorial, you’ll become an Alexa Python developer by deploying your own Alexa skill. You’ll build an application that users will interact with using voice commands to Amazon Alexa devices. Your skill will respond back with a random joke when invoked by the user!
