• pip 20.1b1 发布, 包含新依赖性解析器
  • GITHUB.COM/PYPA

The beta release of pip version 20.1 has dropped and included the next-generation dependency resolver! The resolver is currently turned off by default because it’s unstable and not ready for everyday use. The pip mainainters do encourage users to try it out, however, and feedback on the new resolver can be submitted by filling out a survey.

• Python 内建 Pathlib 其实很棒
  • REDOWAN DELOWAR
  • • Shared by Redowan Delowar

Python 3’s pathlib module has taken some time to gain traction since it was introduced in Python 3.4. After all, the os.path module had been the de facto tool for working with paths in Python. Why change code that works? Learn why pathlib is a better choice for working with file paths in Python in this thorough tutorial.

• Pytest 实效 Python 测试

• 新参者: Guilty 是值得拿来构建新项目的
  • REDDIT

“So here’s the thing. I’m building some cool web apps and have a pretty good understanding of what I’m doing. However, I always feel kinda guilty because I didn’t build 100% of it from scratch. I used various libraries to achieve certain functionality. It’s like I cheated my way to completion by using these libraries. Is this normal or am I overthinking?”

Articles, Tutorials and Talks

• 面向初学者的 Python 装饰器
  • SAM IRELAND

If you’ve used a web framework in Python, you’ve probably used a decorator before. But do you know how they work? Do you know how to make your own? Sam Ireland introduces decorators in this beginner-friendly article by first exploring a typical problem in which decorators arise, then gently walking you through a solution.

• 在Rust代码中编写Python - 第1部分
  • MARA BOS

In this series, Mara Bos — creator of the inline-python Rust crate — walks you through developing a Rust crate for mixing Python into your Rust code from scratch. Part 1 teaches you how to work with Python from Rust, create macros, and handle white space.

• 更好的 Notebooks Through CI: 自动测试图形机器学习的文档
  • HUON WILSON
  • • Shared by Tim Pitman

Building a data science library is walking between two worlds: data science is dominated by Python notebooks, a fast and convenient way to experiment and demonstrate code in the browser, while software engineering focuses on making software reliable and repeatable. Learn how StellarGraph, a graph machine learning library built on Tensorflow and Keras, uses continuous integration to keep the benefits of both.

• HPy: 种面向未来的扩展 Python 方法?
  • ANTONIO CUNI

“HPy is a joint project which is being developed by PyPy, CPython and Cython developers. It aims to design a better C API for writing Python extensions which is more friendly to alternative implementations and which would allow CPython itself more freedom to experiment (e.g. by using a real GC instead of refcounting).”
