Currently they are compiled as nested functions. Benchmarking shows that treating list, dict, and set comprehensions as in-line code can result in a 2x speedup on the comprehension. Python 中的迭代器和可迭代对象: 运行高效的迭代 REAL PYTHON In this tutorial, you’ll learn what iterators and iterables are in Python. You’ll learn how they differ and when to use them in your code. You’ll also learn how to create your own iterators and iterables to make data processing more efficient. (是也乎: 嗯哼, 怎么说呢? 同样是迭代处理,对比一下 Rust 最常见的: 这种链式闭包联级处理, 也是 Elixir/Haskell/LISP/…函数式语言常见的形式, 这在 Python 中还很难日用起来… ) Pandas 2.0 和 Arrow Revolution（上） MARC GARCIA This article details the changes in the Pandas 2.0 release, with emphasis on the underlying adoption of Apache Arrow. 探讨/吐糟 Discussions ...

Have you heard of a Python library with optimized data structures and built-in operations that can speed up your data science code? This week on the show, Jodie Burchell, developer advocate for data science at JetBrains, returns to share secrets for harnessing linear algebra and NumPy for your projects. (是也乎: 简单的说使用数学工具,而不是编程工具. ) Python 的 Multiprocessing 性能问题 ITAMAR TURNER-TRAURING While multiprocessing allows Python to scale to multiple CPUs, it has some performance overhead compared to threading. This article details why processes have performance issues that threads don’t, ways to work around it, and a sample bad solution.

You’ll explore output stream buffering in Python using code examples and learn that output streams are block-buffered by default, and that print() with its default arguments executes line-buffered when interactive. (是也乎: 制作进度条的关键技巧… ) 潜伏在异步代码中的 Heisenbug WILL MCGUGAN When using the create_task() function in asyncio it is very important to maintain a reference to the created tasks. Although this requirement is documented, it is easy to forget and can have some very hard to understand consequences. SQLAlchemy 2.0 有什么新功能? MIGUEL GRINBERG SQLAlchemy 2.0 was launched in January.

This interview with David Vujic discusses monorepos and the set of Python tools that can help you succeed with this pattern. (是也乎: 也就是巨大石仓库,Google 引发的潮流… 其实吧,如果没有合理的配套商业模型以及基础设施和对应专业运维团队, 这么搞….囧的 ) 用 Python 和 SpiffWorkflow 的业务流程模型 REAL PYTHON PODCAST Can you describe your business processes with flowcharts? What if you could define the steps in a standard notation and implement the workflows in pure Python? This week on the show, Dan Funk from Sartography is here to discuss SpiffWorkflow.
