Facebook recently open-sourced Instagram’s Cinder runtime, Pyston 2 returned as an open-source project, and the Pyjion project from Microsoft continues to grow. But Python creator Guido van Rossum has suggested that Python developers in need of more performance should consider writing parts of their code as C extensions, or use the PyPy runtime. This article explores Pythons turbulent history with performance optimization. (是也乎: 对运行时性能的追求, 在 Python 宇宙引发了一系列有益的动荡… ) 性能如何成为安全 Python 代码的克星 DIMA KOTIK While JIT compilers compete for Python performance improvements and some teams rush into asyncio adoption, one has to wonder what the outcome of additional complexity will be. This opinion piece argues that the cost of hurried and potentially unnecessary performance optimization is unstable and insecure code. It’s a good reminder that decisions about project dependencies should be thoroughly researched and made deliberately.

C扩展的隐藏性能开销 原文: PyCoder’s Weekly - Issue #471 210505 Zoom.Quiet(大妈) 用时 42 分钟 完成快译 210505 Zoom.Quiet(大妈) 用时 37 分钟 完成格式转抄. Python C扩展的隐藏性能开销 ITAMAR TURNER-TRAURING It’s no secret that Python is slower than compiled languages like C, C++, and Rust. If you need a performance boost, you can write compiled Python C extensions. But there are some hidden performance costs that you should be aware of if you decide to do this. This article explains two ways that Python C extensions can actually be slower than pure Python and discusses some solutions and work around for them. (是也乎: 是的, Py 内建模块是宝藏, 很少有人都用过的… ) 如何用 ipywidgets 令 Jupyter Notebook 能交互式 MATT WRIGHT Jupyter Notebooks are great for exploratory data analysis. They’re also a good way to share results and analysis with other people, who can alter the notebook to further explore the data themselves. But there are some limitations to notebook interactivity. That’s where ipywidgets comes in! In this tutorial you’ll learn how to create widgets like check boxes, drop-down menus, sliders, and how to handle events like button clicks.
