  • Python 初学者友好与对高级用户支持功能之间纠结
    • ANDRÉ ROBERGE Python has made some big improvements to tracebacks in recent versions. See how tracebacks have evolved over the last couple of major releases and where there’s still some work left to be done. Check out the discussion on Hacker News.
  • 在 Cython 中实现 C++ 虚函式
    • JUAN DIEGO CABALLERO

探讨/吐糟

Discussions

  • Python 内联缓存很成功
    • RAYMOND HETTINGER “In 3.9, access to builtins and globals had sped-up considerably. In 3.10, regular attribute access and access to slots are also faster. Most everyday Python programs will benefit. This is a huge win.”

Articles, Tutorials and Talks

  • Homebrew Python 并不适合您
    • JUSTIN MAYER
    • opinion Installing Python on macOS with Homebrew is pretty easy, but it comes with some quirks that might not make it the best choice for your development environment. Learn why you might not want to install Python this way and how to fix some common issues you might encounter with Homebrew. (是也乎: Homebrew 毕竟是个人作品, 在 官方没有介入前, 只能说可用, 不应该作为生产环境. )
  • Python 开发人员专用 C 和 Dash 数据可视化
    • REAL PYTHON
    • podcast Are you interested in building interactive dashboards with Python? How about a project that takes a flat data file all the way to a web-hosted interactive dashboard? This week on the show, David Amos is back, and he’s brought another batch of PyCoder’s Weekly articles and projects. (是也乎: podcast )
  • 所有 Python 都很慢/但有些则比其他的要快
    • ITAMAR TURNER-TRAURING Python is not the fastest language around, so any performance boost helps, especially if you’re running at scale. It turns out that depending where you install Python from, its performance can vary quite a bit: choosing the wrong version of Python can cut your speed by 10-20%. (是也乎: 参考沈游侠的嗯哼, Python 快其实并不在运行时, 而是整个工程推进的速度哪. )
  • 如何加快 Scikit 学习模型训练
    • MICHAEL GALARNYK
    • • Shared by Michael Galarnyk Sometimes scikit-learn models can take a long time to train. In this article, you’ll explore three approaches to optimizing the model training process. (是也乎: 调整参数之后… )
  • Python 内部函数: 有什么用?
    • REAL PYTHON Learn what inner functions are in Python, how to define them, and what their main use cases are. (是也乎: 好就好在内建, 不用任何额外安装管理… Inner )

    • MASON EGGER
    • • Shared by Mason Egger Learn how to build a Discord bot and host it on the DigitalOcean platform. (是也乎: Discord 是叕一个 Slack 竞品? )
  • Qt Designer 和 Python: 更快构建 GUI 应用
    • REAL PYTHON Learn how to use Qt Designer to create GUIs from your windows and dialogs and use them in your Python applications. (是也乎: Designer 其实, 真不如手写… )
