The Python Software Foundation Packaging Working Group is receiving funding to work on the design, implementation, and rollout of pip’s next-generation dependency resolver. Funding has been allocated to secure a senior developer and an intermediate developer, starting in December 2019 or January 2020. RFP open now through November 22.

The co-creator of Django explains his Python environment: “My setup pieces together pyenv, poetry, and pipx. It’s probably a tad more complex than is ideal for most Python users, but for the things I need, it’s perfect.” Related discussion on Hacker News.

来了, 又来了, 每年更新最具有引战体质话题...

pipenv 被弃用非常明智... )

Python list comprehensions make it easy to create lists while performing sophisticated filtering, mapping, and conditional logic on their members. In this tutorial, you’ll learn when to use a list comprehension in Python and how to create them effectively.

(是也乎:

Comprehension

最讨巧也最容易滥用的技巧...

简单说:

在应该使用时

“Don’t be afraid to create new, more specific data types for your specific use cases. It’s okay to represent different data, used for different purposes, with different data structures, and makes later generalization easier!”

(是也乎:

毕竟 Python 内置的, 而对其它对象的分析, Python 生态中工具也是最多的...

所以, 嫑怕, 放心定制自己舒服的... )

In this tutorial, you will learn how to automatically detect natural disasters (earthquakes, floods, wildfires, cyclones/hurricanes) with up to 95% accuracy using Keras, Computer Vision, and Deep Learning.

GitHub has published its latest State of the Octoverse report which provides fascinating insights into the development industry.

(是也乎:

第一当然是 JAVA 了, 报告中还有其它有趣的结论:

谁是增长最快的语言? 哪个编辑器最受欢迎...

当然, 无论调查如何, 自己舒服的才是最好的.

“We needed a Python interpreter that can be shipped everywhere. You won’t believe what happened next!”

(是也乎:

简单说, 用专用工具来完成...别自己乱来... )

(是也乎:

除了 this 模块之外, 在各种领域都散落有官方一直没注意到的神奇模块, 当然, 多数都是和大数据相关的, pandas 插件, 数据清理/探索, 以及性能检测什么的...

值得逐一尝试体验...

简单说 datetime 才是最好的选择. )

Articles, Tutorials and Talks

Python lambdas are little, anonymous functions, subject to a more restrictive but more concise syntax than regular Python functions. Test your understanding on how you can use them better!

(是也乎:

真蟒 少见的随堂测试, 大家可以尝试一下看对 Lambda 应用场景理解的是否嗯哼

)

“In this episode, Kelly and Sean discuss plausible trends in machine learning, artificial intelligence, augmented and virtual reality, and data science that we may see in schools by 2024. We focus on 5 areas from microscale in the classroom to macro across the entire educational system.”

(是也乎:

未来的教育中, Python 应该什么样?

AI 将泛滥, 工具将更加丰富, 老师将更加无力, 学生自主行为必然得到越来越大的加强

)

Learn about coroutines in Python by example. More specifically, you’ll see how to handle coroutines using asyncio.

In this course, you’ll learn how to work with recursion in your Python programs by mastering concepts such as recursive functions and recursive data structures.

(是也乎:

Recursively

递归...其实, 至今见过最精巧的 Recursively 都是在 LISP 生态中...

)

Exploring a Tornado use case in low memory environment.

(是也乎:

Tornado 严格意义上并不是框架, 而是基础组件, 当然, 也可以独立使用, 所以, 在小内存环境中很得趣...

)

(是也乎:

叕一个模块依赖管理思路... 只是, 第三方没什么好说的, 一但定型都是固定的, 工程内部自制模块的管理才是困难点吧...

)

(是也乎:

等等, 这有什么好比较的? 关注方向都相反的吧...

)

(是也乎:

一半都是5年以上老框架了,,,,而且多数都是专注 RESTful API 生成的, 并不是通用 web 应用框架

)

好物

Interesting Projects, Tools and Libraries, Projects & Code

(是也乎:

SeleniumBase

首先, 还是得起一个完整的 浏览器哪...
