"The Python 3.8 beta cycle is already underway, with Python 3.8.0b1 released on June 4, followed by the second beta on July 4. That means that Python 3.8 is feature complete at this point, which makes it a good time to see what will be part of it when the final release is made."

(是也乎:

已经开始期待 Py 4 了... 在老爹有生之年..应该规划好 Python 42 前所有开发呢.

)

"In some recent discussion on Reddit, I claimed that, for cases where I'm already using flake8, it seemed as though 95% of Pylint's reported problems were false positives. Others had very different experiences, so I was intrigued enough to actually do some measurements."

Learn how to read and understand the information you can get from a Python traceback. You'll walk through several examples of tracebacks and see how to handle some of the most common types of exceptions in Python.

In this article, you'll take a look at the best use cases for Django and Flask along with what makes them unique, from an educational and development standpoint.

(是也乎:

Bottle 一生推...

不过,商业项目, Django 没问题.

Articles, Tutorials and Talks

Interesting recap of the author's experience creating a single-file executable of a Python application using four different tools: Cython, Nuitka, PyOxidizer, and PyInstaller.

(是也乎:

除了 PyOxidizer , 都是传统的 Py 应用打包思路; PyOxidizer 比较清奇, 将核心运行时, 用 Rust 包装起来, 获得更加安全和高效...

只是, 还在早期, 尝试过, mac 下都编译不过, win10 更加没戏...

远没有 golang build 支持树来的嗯哼...

)

A 4-post series that provides a fundamentals-oriented approach towards understanding Neural Networks.

A detailed guide to creating production-ready Docker images for your Python applications.

(是也乎:

无论是否在 Docker , Python 运行时环境都应该和系统 Python 运行时区分, 又合理调用

)

"I'm going to try, in this post and the ones that follow, to shed some light on the meaning of – and a little of the etymological history behind – the fundamental units of Python fluency. In this first part we will start with the most basic of those units, Python's 35 keywords."

In this tutorial, you will learn how to use Cyclical Learning Rates (CLR) and Keras to train your own neural networks. Using Cyclical Learning Rates you can dramatically reduce the number of experiments required to tune and find an optimal learning rate for your model.

In this step-by-step Python tutorial, you'll not only take a closer look at the new Django migrations system that is integrated into Django but also walk through the migration files themselves.

Migrations 工具桟可以说是 Django 的命门, 一直修炼的非常 NB 了...

当然, Django only, 想提取出来单独用, 不现实.

A tutorial on how best to reason about and structure ETL jobs written for PySpark, so that they are robust, reusable, testable, easy to debug and ready for production.

"While this research demonstrates a fundamental break in the Python 3.2 (or below) hash algorithm, Python fixed this issue 7 years ago. It's time to upgrade."

(是也乎:

Python 3.2 之后解决了...

)

In this episode of Teaching Python, Sean and Kelly discuss their top 5 favorite editors for teaching (and learning) Python.

(是也乎:

注意, 教学用...

Mu Editor
Visual Studio Code
PyCharm Edu
python.microbit.org
Repl.it
Jupyter

嗯嗯嗯...怎么说呢... 能和生产环境一致是最合算的事儿...

(是也乎:

K8s 是 google 叕一次统一领域技术思想的杀手...

(是也乎:

同下, 最重要的总是:

知道何时住手

(是也乎:

其实, 列表推导式, 最重要的技巧是:

知道, 何时应该不用

(是也乎:

叕一个私人 PyPI 实现...

但是, 对于中国, 要的是高速镜像...

总是永远有人问这个问题... 当然, 这个问题任何一个技术社区都有人在问...

其实, 本质上并不是对应技术是否有什么能力, 而是相反...
