“COVID-19 has changed all aspects of our lives and is reshaping our future. Nonprofits like the PSF are having to rebuild. With PyCon 2020 and 2021 happening virtually, the PSF is faced with potentially losing $1.2 million USD of expected revenue for those two years. This fundraiser is critically important and the money raised will help the PSF support the tools and initiatives that Pythonistas use everyday.”

• 建立自己的国际象棋引擎
  • ANDREW HEALEY

Writing your own chess engine is a great way to explore computational complexity and combinatorial aspects of programming. Not to mention it’s pretty fun! Follow along with this reflection on how one coder created his own Chess engine from scratch.

• 用 Python pickle 模块序列化对象
  • REAL PYTHON
  • course

Learn how you can use the Python pickle module to convert your objects into a stream of bytes that can be saved to a disk or sent over a network. You’ll also learn the security implications of using this process on objects from an untrusted source.

(是也乎:

等等, 官方已经不推荐用 pickle 了哪..

• Python 真的是瓶颈吗?
  • ANNA ANISIENIA

Python is slow. From one perspective, that is. But what are the true bottlenecks in the data engineering/data processing space, and how does Python compare to other technologies when those factors are considered?

(是也乎:

工具的瓶颈并不是工程的, 人思想的瓶颈才一直是.

• 用 PyQt 的 QThread 防止 GUI 冻结
  • REAL PYTHON

In this step-by-step tutorial, you’ll learn how to prevent freezing GUIs by offloading long-running tasks to worker QThreads in PyQt.

(是也乎:

其实, 就是 Qt 不得不接管系统的各种职责在完成自我控制.

Articles, Tutorials and Talks

• 如何用 np.linspace 管理内存和创建数组
  • REAL PYTHON
  • podcast

Have you wondered how Python manages memory? How are your variables stored in memory, and when do they get deleted? This week on the show, David Amos is here, and he has brought another batch of PyCoder’s Weekly articles and projects. Along with the Real Python article on Python memory management, we also talk about another article about creating even and non-even spaced arrays in Python with np.linspace.

(是也乎:

等等, 上周也说了这事儿? 是系列?

• 用 Python 和 Scikit-Learn 进行 OPTICS 聚类
  • CHRISTIAN VERSLOOT

Clustering is a big part of unsupervised machine learning. Since no labels are available, data point must be grouped, or clustered, based on some similarity measure. OPTICS is a clustering algorithm, and in this article you’lol learn how to use it with the Scikit-Learn library.

• pass 语句: 如何在Python中无所事事
  • REAL PYTHON

In this tutorial, you’ll learn about the Python pass statement, which tells the interpreter to do nothing. Even though pass has no effect on program execution, it can be useful. You’ll see several use cases for pass as well as some alternative ways to do nothing in your code.

• 用 Python 可视化 Mandelbrot 集
  • BLAKE SANIE

The Mandelbrot set is fractal and infinitely self-similar. Fortunately, you can write a finite Python program to visualize it! Have some fun creating beautiful pictures with this tutorial.
