This is a proof-of-concept implementation of CPython that supports multithreading without the global interpreter lock (GIL), from Facebook research. An overview of the design is described in the Python Multithreading without the GIL Google doc. Also see the related discussions on LWN and Hacker News.

“The setuptools team no longer wants to be in the business of providing a command line interface and is actively working to become just a library for building packages. What you should do instead depends on your use case, but if you want some basic rules of thumb, there is a table in the summary section.”

“One of the tasks given me by the Python Software Foundation as part of the Developer in Residence job was to look at the state of CPython as an active software development project. What are people working on? Which standard libraries require most work? Who are the active experts behind which libraries?”

In this course, you’ll explore some of the coolest and most useful features in Python 3.10. You’ll appreciate more user-friendly error messages, learn about how you can handle complicated data structures with structural pattern matching, and explore new enhancements to Python’s type system.

“Since Python 3.5 was released in 2015 including PEP 484 and the typing module type hints have grown from a nice-to-have to an expectation for popular packages. To fulfill this expectation our team has committed to shipping type hints for the v2.0 milestone. What we didn’t realize is the amount of value we’d derive from this project in terms of code correctness.”

嗯哼?这种基础库, 能不动就嫑动./ )

Earlier this year, the Python Software Foundation announced the creation of the Developer in Residence role. The first Visionary Sponsors of the PSF have provided funding for this new role for one year. What development responsibilities does this job address? This week on the show, Łukasz Langa talks about becoming the first CPython Developer in Residence.

In this course, you’ll learn about assignment expressions and the walrus operator. The biggest change in Python 3.8 was the inclusion of the := operator, which you can use to assign variables in the middle of expressions. You’ll see several examples of how to take advantage of this new feature.

(是也乎:=

In this tutorial, you’ll learn what XML parsers are available in Python and how to pick the right parsing model for your specific use case. You’ll explore Python’s built-in parsers as well as major third-party libraries.

“Today while running an apt full-upgrade I asked myself how apt does this nice progress bar stuck at the bottom line while still writing scrolling text.” Python example code included.

(是也乎:

不是, 再有趣的进度条能给最终用户带来什么提升? 只是运维看着舒服哈?

Guidelines for config management in general and for Python apps in particular. Why “Configuration is just another API of your app” might be a good philosophy to adopt.

In this step-by-step tutorial, you’ll learn how to create managed attributes, also known as properties, using Python’s property() in your custom classes.

不觉中蟒周刊快译已经到了第9个年头

去年开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时:
    what f**k 还能这样玩? 还有这东西?
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
