  • Python 软件基金会 2020 募捐
    • PYTHON.ORG “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 $1.2 million USD of expected revenue for those two years. This fundraiser is critically important and the money raised will help the PSF support the tools and initiatives that Pythonistas use everyday.” (是也乎: Pythonistas 年度咨文, 值得动员日本分部漫画化. 将今年损失的 120万$ 找回来. )
  • 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. (是也乎: 反正, 没人折腾 go 的. )
  • 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: Serializing 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: QThread 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? podcast )
  • 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. (是也乎:

无为而治 pass )

  • 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. (是也乎: Mandelbrot 用不到50行代码, 就可实现无限分形的绘制… 只引用了: from PIL import Image import colorsys import math import os 核心就是 math 标准计算. )
  • 用 Python 生成 STL 模型
    • CARLO SUPINA Learn how to use the numpy-stl library to create STL files that can be loaded into CAD software and used to create 3D printed shapes.
  • 基于Django 会话的 Auth 用以单页应用程序
    • NIK TOMAZIC
    • • Shared by Michael Herman Learn how to add session-based authentication to a Single-Page Application powered by Django and React. (是也乎: 所以, Django 也开始 Liveshow, 向 Phoenix 学习? )
  • 佛罗里达的 Python 嗅探犬开始成功追踪入侵物种
    • ANN SCHMIDT Watch out pythons! These dogs are on your trail.
