The award goes to the programming language that has gained the most popularity in one year, with Python rising by 2.01% in 2020. (是也乎: 感谢 COVID-19 ? 无数预测/分析都是用 Py 制作的, 当然, Guido 老爹入住 M$ 也是一种成圣仪式? 只是, Python 无论多好,我们自己无法用 Py 构造自己的睡后收入, 也只能是爱好而已. ) Python 幕后: Python 属性如何工作 VICTOR SKVORTSOV Take a deep dive into how Python attributes work, including a detailed analysis of the CPython code. 用 Tox 进行 Python 测试和打包的最佳实践 HYNEK SCHLAWACK How to ensure that your tests run code that you think they are running, and how to measure your coverage over multiple tox runs (in parallel.) (是也乎: tox 这工具, 俺知道有5年多了, 但是, 没见国内有人用过哪… 为什么? ) 用 Django REST Framework/DRF 构建 HTTP API REAL PYTHON course Django REST framework (DRF) is a toolkit built on top of the Django web framework that reduces the amount of code you need to write to create RESTful HTTP APIs.

In this article from the NVIDIA Developer Blog, you’ll learn how to leverage C++ in Python using Cython and the nvc++ library. There’s even a real-world example that illustrates the Jacobi method to solve a heat equation. 从 Github 下载了 10,000,000 Jupyter 笔记本: 学到的东西 ALENA GUZHARINA The JetBrains Datalore team downloaded ten million Jupyter Notebooks and analyzed them to determine things like which languages were the most popular, what kinds of content are in notebook cells, and how consistently notebooks can be reproduced. It’s a fascinating look into trends in data science technology! (是也乎: 千万级别的 Jupyter 流行度分析. 这很 JetBrain ) Django 管理员自定义 REAL PYTHON course Learn how to customize Django’s admin with Python. You’ll use AdminModel objects to add display columns, calculate values, link to referring objects, and search and filter results. You’ll also use template overriding to gain full control over the admin’s HTML. 解答布尔运算 BRETT CANNON In the latest entry to his series on syntactic sugar, Brett Cannon explores boolean expressions. You’ll learn how boolean expressions “short circuit” and, as an unexpected bonus, a peek into how CPython “cheats” at variables. 值得了解:2020年十大Python库 ALAN DESCOINS This listicle is full of Python projects that you really should know about! Each library on the lists was launched or popularized in 2020 and has seen steady maintenance since its launch. Lots of great projects here! (是也乎: Typer 绝对是惊喜, 作为 FastAPI 的 CLI 版本, 感觉只是游戏之作, 但是, 在 CLICK 之上, 融合 FastAPI 的气质, 立即大热… 当然, 俺还是用 Invoke(来自 Febric 的习惯…) tryolabs.com 每年总结 top10 模块, 已经有年头了, 品味没毛病. ) 2020 年 Real Python 创作回顾 REAL PYTHON podcast It’s been quite the year!
