8 surprising things I learned about Python in 2021
======
Opensource.com authors shed light on new ways to use the popular
programming language.
![Hands on a keyboard with a Python book ][1]
Python has long been one of the most popular programming languages, but that doesn't mean there's nothing new to learn. This list of Opensource.com's most-read articles about Python is an excellent place to start. 
* Widespread adoption of machine learning is here, and its applications are still growing. See how machine learning, using [Naïve Bayes][2] classifiers and implemented with Python, can solve real-life problems.
* The transition to Python 3 is complete, but enhancements keep coming. Seth Kenlon highlights [five hidden gems in Python 3][3] that stand out among recent improvements.
* Openshot has been one of the best options for Linux video editing for years. This popular article will show you how you, too, can [edit video on Linux][4] with this Python app. 
* The best part of Python is the limitless possibilities a programmer can achieve. [Cython][5] is a compiler that will not only help speed up code execution but also let users write C extensions for Python.
* Python can make API unit testing simpler. Miguel Brito shows you [three ways to test your API][6] with Python.
* As computation power increases, more and more programs run concurrently. That can make it challenging to debug, log, and profile what's going wrong. [VizTracer][7] was created to solve exactly that problem.
* Users' personal projects, big and small, are a good reminder of how much fun open source coding can be. Here's an inspirational one: how Opensource.com author Darin London [monitors his greenhouse][8] using CircuitPython.
* Linux users often encounter programs requiring a lot of command-line arguments that are not pleasant to work with. This is a [nice configuration parsing hack][9] to make life easier.

我在 2021 年学到的关于 Python 的 8 个令人惊讶的东西
======
Opensource.com 的作者们揭示了使用这一流行的编程语言的新方法。
![Hands on a keyboard with a Python book ][1]
长期以来Python 一直是最受欢迎的编程语言之一但这并不意味着没有什么新东西可学。Opensource.com 上关于 Python 的阅读量最大的文章列表是一个很好的开始。
* 机器学习的广泛采用已经到来,其应用仍在增长。看看使用 [Naïve Bayes][2] 分类器并通过 Python 实现的机器学习如何解决现实生活中的问题。
* 向 Python 3 的过渡已经完成但增强功能不断涌现。Seth Kenlon 强调了[Python 3 中的五颗隐藏的宝石][3],它们在最近的改进中脱颖而出。
* Openshot 多年来一直是 Linux 视频编辑的最佳选择之一。这篇受欢迎的文章将告诉你,你也可以用这个 Python 应用[在 Linux 上编辑视频][4]。
* Python 最好的部分是一个程序员可以实现的无限可能。[Cython][5] 是一个编译器,不仅可以帮助加快代码执行速度,还可以让用户为 Python 编写 C 语言扩展。
* Python可以使 API 单元测试更简单。Miguel Brito 向你展示了[用 Python 测试 API 的三种方法][6]。
* 随着计算能力的提高,越来越多的程序在并发运行。这可能会使调试、日志记录和剖析出错的地方成为挑战。[VizTracer][7] 正是为了解决这个问题而创建的。
* 用户的个人项目无论大小都很好地提醒我们开源编码可以有多大的乐趣。这里有一个鼓舞人心的项目Opensource.com 的作者 Darin London 如何使用 CircuitPython [监控他的温室][8]。
* Linux 用户经常会遇到需要大量命令行参数的程序,这让人很不爽。这是一个[不错的配置解析技巧][9],可以让生活更轻松。
