  • SpaceX 如何降落星舰/排序
    • THOMAS GODDEN While waiting for SN15 to launch, Thomas Goddard set out to pull together a 2-dimensional simulation of the Starship landing. Tying together knowledge of trajectory optimization, Thomas modeled the landing in Python with the CasADI library and used Matplotlib to generate an animation which, when played side-by-side with the footage of the landing, results in remarkable similarity to the actual landing dynamics. (是也乎: 是的, JS/Py 反正以往 NASA 不用的, SpaceX 都用上了, 关键是 多快好省, 至于现代语言/系统在太空的意外错误, 通过三主机协议选举也就解决了… )
  • Flask 2.0中的异步
    • PATRICK KENNEDY
    • • Shared by Patrick Kennedy This article looks at Flask 2.0’s new async functionality and how to leverage it in your Flask projects. You’ll learn how Flask processes requests asynchronously using a traditional WSGI server, instead of the ASGI server used by many other async web frameworks. You’ll also learn how to simulate Flask 2.0 async in Flask 1.X applications.
  • 嵌入式Python/ 在BBC micro:bit上构建游戏
    • REAL PYTHON Learn about embedded development, an exciting area of programming that allows you to bring your code into the physical world. You’ll learn about your options for writing embedded Python code and build a basic game using the BBC micro:bit. (是也乎: BBC 是的, 就是那个 BBC )
  • EuroPython 2021 议题投票已开放
    • EUROPYTHON.EU Planning on attending EuroPython this year? If you’re registered and have paid for a ticket, or if you’ve attended any of the past conferences, you can vote on talk submissions until May 23. (是也乎: 其实, 很多都是从 US 复场过来的 )

  • The 2021 Python 语言峰会
    • PYTHON SOFTWARE FOUNDATION Every year the Python Software foundation hosts the Python Language Summit where a small group of core developers discusses the current state and future direction of the Python language. Check back regularly on this announcement to find links to writeups about the events from the summit, penned this year by Real Python’s Joanna Jablonski. (是也乎: 老爹放卫星了… )
  • 在 2021 年为 PyPI 提供动力
    • DUSTIN INGRAM What does it take to power PyPI in this current day and age? Learn what technologies PyPI uses, who is involved, how much it costs, and how you can help support the package index. (是也乎: 去年至少有两次不可用事故, 而且长期无法 search , 可见 PyPI 很成问题了… )
  • 用 Arcade 构建平台游戏并每月报道 Python 新闻
    • REAL PYTHON
    • podcast Did you know the Python Software Foundation is hiring! With the recent support of three Visionary Sponsors, the PSF has been able to open positions for a developer-in-residence and a Python packaging project manager. Real Python now has a monthly Python news article. Frequent guest of the show, David Amos compiles and summarizes the biggest Python news from the past month. (是也乎: Game 卷轴游戏,永远的经典… )
  • 用DuckDB在 Pandas 上进行高效的SQL
    • MARK RAASVELDT AND HANNES MÜHLEISEN
    • • Shared by Alexander Monahan pandas is an indispensable tool for Python data analysis. It’s also a standard for data transfer between elements of the Python data ecosystem. But sometimes you need some good ol’ SQL in your data workflow. With DuckDB, you can perform SQL queries directly against pandas data frames. DuckDB is faster than pandas in some cases and can even handle larger-than-memory data. (是也乎: 无论 Pandas 将数据集操作折腾的多么 Pythonc, 对于广大财务人员而言, 还是 SQL 更加值得信赖. )
  • Unravelling the pass Statement
    • BRETT CANNON When you need to indicate that a bit of code intentionally does nothing, then you need to reach for Python’s pass statement. In the latest installment of Brett’s “Syntactic Sugar” series, you’ll learn how pass works, when to use it, and why it’s a uniquely Python concept.
  • 用 namedtuple 编写干净的 Pythonic 代码
    • REAL PYTHON In this step-by-step tutorial, you’ll learn what Python’s namedtuple is and how to use it in your code. You’ll also learn about the main differences between named tuples and other data structures, such as dictionaries, data classes, and typed named tuples. (是也乎: namedtuple 记得 Limodou 为了方便 UliEidtor 的开发, 还专门设计了一个类似的类… )
  • 使用 Python 或运算符
    • REAL PYTHON
    • course In this step-by-step course, you’ll learn about how the Python or operator works and how to use it. You’ll get to know its special features and see what kind of programming problems you can solve by using or in Python. (是也乎: or 逻辑计算基础算子 )
