PEP 703: 在 CPython 中使 GIL 可选
- PYTHON.ORG This PEP proposes changes to the CPython build process that would allow you to build a GIL-less interpreter. This kind of interpreter would not be ABI compatible with the GIL-based one, and the programmer would become responsible for some locking situations in C-extensions. If implemented, this would lead the way to being able to operate without the GIL in cases where backward compatibility issues are not important. (是也乎: 嗯哼? 就象 Rust 中的 unsafe ? )

Python 特性小回顾
- BRETT CANNON “To help those who wish for the ‘good old days’ of some older Python version, I thought I would write down a bunch of the major language features that were added in Python in reverse chronological order. Start from top and work your way down until you come across a feature you aren’t willing to give up. The Python version which has that feature is the version you would be okay going back to.” (是也乎: 这几年 Python 中追加的特性是过去30年追加的总合还要多吧? )

Excel/Python 和数据科学的未来
- MATT ASAY What’s the most widely used tool in data science? Is it pandas or NumPy? Is it the Python language itself? Not really. It’s Excel. You might argue that data scientists aren’t using Excel as their primary tool, and you might be right. But Excel enables non-technical users, like small business owners, to gain insights into their data. In this article, Anaconda CEO Peter Wang discusses his goal of making Python and PyData the “conceptual successor” to Excel. (是也乎: 对的, 无论 Jupyter 怎么折腾, 如果 Excel 嵌入 Python, 那么瞬间, 没 notebook 什么事儿了… )

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.

真实场景中： 1、异步 web 服务器不可使用 reverse proxy，因为 async server 性能高于 reverse proxy。瓶颈位置在 reverse proxy 和 wsgi 层而非 web server。使用 reverse proxy 是因为多线程 context 切换成本高，开不了很多，所以需要一个能无限开 context 的异步服务器（nginx）挡在前面。而本身异步的服务器不需要。 2、异步 web server 不可使用 connection pool 和消息队列，因为无论是协程还是纯单线程异步，协程数和连接数都用不完。由于不存在多线程或者多进程的 context 切换成本，导致只能起有限的线程数，所以需要连接池。异步的连接数用不完，所以不需要连接池，否则会成为瓶颈。 3、异步服务器在并发数超过 1000 时才会明显体现出来，sync 服务器即使在使用 reverse proxy 的情况下由于中间的代理损耗也很难处理 1000 以上的并发。我在对异步服务器做性能测试的时候，是测试程序先挺不住，真实测试异步服务器的性能的技术含量不低，初学者做不到。这篇作品槽点太多，先说以上几点。一个个讲过来，要打一天的字。 <– 摘录隔壁群中对此文章的部分观点. 简单说, 对异步和协程的理解, 文章测试出发点就有问题. )

全文如下: The Mind at Work: Guido van Rossum on how Python makes thinking in code easier By Anthony Wing Kosner Published on November 25, 2019 A conversation with the creator of the world’s most popular programming language on removing brain friction for better work. Nothing defines the 21st century more than the ubiquitous effects of computer programming. Almost everything we do, particularly at work, is mediated by screens displaying the results of the enormous amount of computation that we now take for granted. If you’re one of the 99.7% of the human race that are not programmers, how all of this happens is a bit of a mystery. As science fiction writer Arthur C. Clarke quotably wrote, “Any sufficiently advanced technology is indistinguishable from magic.” Of course, it isn’t magic. It is, however, both complicated and complex, with codebases of tech companies measured in millions of lines of code. When you’re reasoning about a real system you might want to build in code, you’re thinking about the complex relationships between different functions over time. Your code can be more or less complicated in how it is written and structured, but the problem you’re trying to solve has an inherent complexity that can’t be reduced to something simpler. Becoming a programmer is not just about ideas, and you won’t last long at it if you can’t deal with the laser-focused details of describing your ideas in code. “I’m a little skeptical of the claim that the systems thinking is primary there, because it’s much easier to come up with an idea for a system than it is to take an idea and turn it into working code,” says Guido van Rossum, the creator and retired BDFL (Benevolent Dictator for Life) of the Python programming language. JavaScript still owns the web, and Java runs 2.5 billion Android phones, but for general purpose programming and education, Python has become the default standard. If anyone has made turning an idea into working code easier, for more people, it’s Van Rossum over his 30-year history with Python. And he’s done it with a self-effacing grace and an understated humor—the language is named after the surreal comedy of Monty Python, not the actual Burmese python. In its quiet way, the Python programming language has managed to make some of the complications of programming computers less difficult for our brains to manage. To understand how Van Rossum accomplished this amazing feat, we have to go back into the history of computing to the era of mainframes and machine language. “The mainframe is a machine that costs many millions of dollars, and the combined pay of all those programmers is peanuts compared to the cost of the mainframe,” he says, explaining that cost logically prioritized machine time over human time. “But as I experienced desktop workstations and PCs, I realized that a change of mindset about cost of the programmer’s time versus cost of the computer’s time was overdue.” Van Rossum doesn’t think he was the first person to observe this shift, but he really capitalized on it in the design of Python. This simple idea of giving humans priority over machines is at the core of the philosophy behind Python. Certainly the fact that it’s an interpreted language as opposed to a compiled language means that the programmer gets immediate feedback about the code they’re writing without needing to take the time to recompile it after making each change. This is very common now, but thirty years ago it was quite controversial because the conventional wisdom was that faster (for the computer) was better. Updating this belief has had a large positive impact on the productivity of programmers. “In Python, every symbol you type is essential.” —Guido van Rossum “There are a whole bunch of common programming tasks that are easy in Python,” says Van Rossum. “For someone who is not yet a programmer, who wants to become a programmer, for those people Python is particularly easy to get.” Indeed, many computer science schools are switching over from Java to Python, because it’s much easier to grasp for beginners. The reasons behind this are complex, with many factors each reducing little bits of friction. What’s simple is the philosophy behind all of the improvements: Everything should have a necessary purpose. The lack of extraneous code makes it easier to focus on what you need to pay attention to. “In Python, every symbol you type is essential,” Van Rossum says. This concision makes it easy to accomplish something meaningful in Python, which is one of the reasons for its wide adoption. “The typical way that we introduce Python to beginning programmers is also important. We can show them very small snippets of code that require very little understanding of terminology and concepts from programming before they make sense,” Van Rossum explains, “whereas the smallest Java program, for example, contains a whole bunch of what are, to the uninitiated eye, noise characters.” This quietness and simplicity of design makes it easier to see what’s going on. “Python for me is incredibly visual,” says Van Rossum. “When I read Python, I definitely see it as a two-dimensional structure, rather than one-dimensional, like language. That is probably because Python uses indentation for grouping, but probably also because my mind just likes thinking visually.” He’s not the only one, of course, who thinks visually. We all do to some extent. But he’s particularly sensitive to the effects of the visual on cognition. “Some poorly formatted text can drive me crazy. They interrupt my visual parsing of the flow and the structure, and in that sense, I do think in Python,” Van Rossum admits. “I can grasp code much better when it’s formatted properly.” It takes more information to resolve the uncertainty about what code indentations mean if they’re arbitrary than if those indentations have a clear purpose, as they do in Python. So if the experience is easier, it’s because fewer bits of information have to be processed for you to know what’s going on. Python’s readability is not just typographic, but conceptual. Van Rossum thinks Python may be closer to our visual understanding of the structures that we are representing in code than other languages because, “Python makes that structure mandatory.” “While I was researching my book, CODERS,” says author Clive Thompson, “I talked to a lot of developers who absolutely love Python. Nearly all said something like ‘Python is beautiful.’ They loved its readability—they found that it was far easier to glance at Python code and see its intent. Shorn of curly brackets, indented in elegant visual shelves, anything written in Python really looks like modern poetry.” They also find that Python is fun to write, which is more important than it may seem. As Thompson writes, “When you meet a coder, you’re meeting someone whose core daily experience is of unending failure and grinding frustration.” “You primarily write your code to communicate with other coders, and, to a lesser extent, to impose your will on the computer.” —Guido van Rossum Building the priority of the programmer’s time into the language has had a curious effect on the community that’s grown around it. There’s a social philosophy that flows out of Python in terms of the programmer’s responsibility to write programs for other people. There’s an implicit suggestion, very much supported by Van Rossum in the ways he talks and writes about Python, to take a little more time in order to make your code more interpretable to someone else in the future. Expressing your respect for others and their time through the quality of your work is an ethos that Van Rossum has stealthily propagated in the world. “You primarily write your code to communicate with other coders, and, to a lesser extent, to impose your will on the computer,” he says. The universality of the culture that’s spread around Python has achieved some measure of what Van Rossum intended two decades ago with a short-lived project called CP4E (Computer Programming for Everybody). “I’m usually not a very visionary thinker. People always ask me, what’s next for Python, and I never know. But I put on my most visionary hat, and assumed that it would make sense for everyone to learn programming.” Personal computers had been around for 20 years, but mostly they were glorified typewriters and calculators. Van Rossum asked, “isn’t it crazy that all those people have computers, and very few of them learn to program?” In the time since, he has focused on making programming easier to learn and easier to do through the advancements in Python, now at version 3.7. He still thinks that programming teaches generally valuable skills, like problem solving, following directions carefully, and understanding what directions mean. But he’s also found that, “there are certain introductions to programming that are fun for kids to do, but they’re not fun for all kids, and I don’t think I would want to make it a mandatory part of the curriculum.” At the same time, the need for people to program their computers has also diminished because of the growth of software, particularly on the web, that allows you to intuitively do what used to require programing to accomplish. “I’m not so sure that it needs to happen anymore,” Van Rossum says of CP4E. “I think computers have made it to that point, where they’re just a useful thing that not everybody needs to know what goes on inside.” “Python is now also the language of amateurs, and I mean that in the best possible way.” —Guido van Rossum But that are a growing number of people who are using Python in many fields. “The currently prevailing theory about Python’s unexpected success,” says Van Rossum, “is that at some point, it established itself into data science and machine learning, and scientific data processing in general, and once you have critical mass, it’s easier for everyone to use the same system as their colleagues and their competitors, than to try something different.” And even though it started as purely a tool for professional programmers, Van Rossum says, “Python is now also the language of amateurs, and I mean that in the best possible way.” A successful open source software project, like Python, has to be easy to learn for beginners, but also have practical application to real world problems that more advanced users will want to solve. Just as for beginners you want to keep things simple so all of their brain energy is spent on learning the complications of the programming environment, for advanced users you want to help them manage the complexity of these competing abstractions. Part of the motivation for making the implementation of Python as simple as possible is to be able to change your mind, to learn, to iterate. “If you write a prototype in Python and you get it to work, often, that’s not a very big effort,” says Van Rossum, “and then you can afford to throw away your prototype and write the same thing again based on what you’ve learned. You can still write it in Python, but the second version will be much better than the first.” Part of the enduring appeal of Python is the optimism and humility of starting over. “If you’ve invested much more time into writing and debugging code, you’re much less eager to throw it all away and start over.” Co-founder and CEO, Drew Houston wrote the first prototype of Dropbox in Python on a five-hour bus ride from Boston to New York. “The early prototypes of Dropbox were thrown away, largely, many times,” says Van Rossum. What can we learn from Python about how to design better tools for thinking? Tim Peters, one of Python’s major contributors, offers some clues in the aphoristic The Zen of Python, in which he channels Van Rossum’s guiding principles. Particularly relevant to our present discussion are this pair: “Simple is better than complex. Complex is better than complicated.” This could almost be a recipe for how the brain prioritizes its functions to use energy efficiently. Equally important for Van Rossum is the social aspect of thinking and building tools. What has he taken away from his thirty year journey with Python? “I have learned that you can’t do it alone, which is not an easy lesson for me. I’ve learned that you don’t always get the outcome that you went for, but maybe the outcome you get is just as good, or better.” 简单说: Python 之禅 真的包含了老爹所有关键思考成果. )

PEP 570 (仅位参数)已被接受
- PYTHON.ORG This PEP introduces a new syntax, /, for specifying positional-only parameters in Python function definitions. Looks useful for getting tighter control over how a library API can be called (i.e. preventing positional params from being called as keyword arguments). This will also allow for some function call speed optimizations in the future. (是也乎: 严格参数传输,以便优化…反正就是越来越 C++ 呗… 老爹一退休就乱来. )

- MASON EGGER • Shared by Mason Egger How three tools (pyenv, pipx, pipenv) make for smooth, isolated, reproducible Python developer and production environments. (是也乎: 这,是非常重要的常用嗯哼哪… 只是, 一点儿也不简单..因为 Python 中一直就没有一个合理的工具一致性解决所有阶段的开发环境问题: 本地开发时的版本和模块依赖管理测试时高速部署依赖模块运行时自动化同步版本和依赖模块版本 Docker 是一把将所有阶段的环境问题用虚拟机解决了, 只是带来空间无法控制, 以及必须理解并忍受越来越多的专用工具; 所以, 先用已有工具组合为一个合理可理解的工具箱来完成是好的: pyenv 进行本地/测试/生产的运行时版本和模块依赖树隔离在 pyenv 之下.. conda 负责部分大型编译型模块的预编译管理 pipenv 进行模块的依赖/版本管理嗯哼, 就是缺少一环: 可以高速冻结本地模块依赖树, 并能自动化同步模块树镜像到任意指定主机上; 以便从本地安装模块,而不依赖可怜的墙外网速…

再次感叹: dh-virtualenv, 已经解决了这一环的问题…

用 pyenv 管理多个 Python 版本
- REAL PYTHON In this step-by-step tutorial, you’ll learn how to install multiple Python versions and switch between them with ease, including project-specific virtual environments, even if you don’t have sudo access with pyenv. (是也乎: 其实 PyEnv 比 pipenv 灵活就在, 不仅仅是将运行时版本进行了管理, 而且可以简便的将 Python 版本环境, 工程模块依赖环境, 在本地自由结合到任意工程目录上. 就是缺少一个一键将当前环境所有依赖模块冻结为压缩文件, 并能简洁的传送到远方主机, 一键完成再安装配置的工具… 毕竟, 总是有些模块是依赖外部 GCC 之类工具现场编译的. )
2005 年以来 Python 包的增长
- PYDIST.COM “The Python ecosystem has been steadily growing [since 2005]. After the first few years of hyper growth as PyPI gained near-full adoption in the Python community, the number of packages actively developed each year—meaning they had at least one release or new distribution uploaded—has increased 28% to 48% every year.” (是也乎: 每年 28%~48% 的增长, 比中国 GDP 高, 但是远远小于 node.js 的. )
