Python Enhancement Proposal 709 covers a change to how comprehensions are handled. 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.

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.



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...


This article details the changes in the Pandas 2.0 release, with emphasis on the underlying adoption of Apache Arrow.



Last week’s issue of PyCoders included a link to Python’s multiprocessing performance problem which now has a Hacker News conversation to go along with it.



好问题哪, 老爹都退休了...其它同期语言都佛了...

作为 GitHub: Codespaces + Copilot 的硬广是没问题的,

只是囧的,没好意思说 Ruby ...

PS: Codespaces 这么火, 国内的 Coding 应该发财了?



Articles, Tutorials and Talks

The articles discusses whether Python is as slow as so many authors claim. When doing so, it mentions highly optimized Python frameworks for numerical computation, efficient compilers - but also coding time as opposed to execution time. All in all, Python is much faster than most think.

In this introductory tutorial, you will build a recurrent neural network (RNN) with PyTorch. The RNN will be trained to read names and it will output the natural language they belong to. This is a modern spin on a tutorial from the PyTorch documentation.




In this video course, you’ll learn what Python’s namedtuple is and how to use it in your code. You’ll also learn about the main differences between named tuples and other data structures, such as dictionaries, data classes, and typed named tuples.



不是, 听起来已经不象是真人讲解的了...

不过, 这个低调的模块: collections — Container datatypes — Python 3.11.2 documentation

早已在 sqlite3 等等其它关键模块中深入用起来了...


In this tutorial, you’ll learn how to use NumPy reshape() to rearrange the data in an array. You’ll learn to increase and decrease the number of dimensions and to configure the data in the new array to suit your requirements.




Flask is approaching its 13th birthday, and to celebrate, Phillip has written 13 tips for writing modern Flask apps. It covers dealing with JSON, environment based configuration, auto-generated docs, and more.

There are many speed improvements in CPython 3.11, but that doesn’t mean the Python alternatives don’t still have some advantages. Pyston and PyPy are still better in some cases.


Pyston & PyPy 又没有历史包袱...怎么浪怎么来就好...


This tutorial shows you how to build a system that takes a question template and writes a resume as output. The example is built on Streamlit and OpenAI.


等于自动帮你对比全球成功获得 offer 的简历, 进行对应优化...


Elixir is a functional based programming language with similarities to Ruby and Python. This article is an intro guide for programmers who know Python.


所以? Python 其实成了IT世界的英语? 先会 Python ,然后, 其它的水到渠成?


Python’s addition of typing has created “two” languages: typed and untyped Python. Tin tells you why that’s a great thing.


c'est la vie (´-ι_-`)

不过, 不用类型提示的应该永远支持, 这毕竟是更加直觉的一类...


This step-by-step tutorial shows you how to build a rust tool and deliver it through Python packaging mechanisms.


嗯哼? 这个赞的哪...刚刚学会如何用 Rust 快速开发 CLI, 和 invoke/Click/... 相比, 还是复杂了点儿..

已经发布的小工具: ZoomQuiet crates.io: Rust Package Registry

部分根本就是照着原先 Python 版本逐行迁移过去的...


Quick instructions on using nox with parameters to test multiple versions of Python against your test suite.


Interesting Projects, Tools and Libraries, Projects & Code


这种教程的趋势是先越来越短,现在不行不越来越长? 21天精通XXXX 流行了几年, 后来就是一天掌握XXX...



实话, 都在内存里了,想性能低一点儿, 反而难的卟?



LLVM 成名后, LL 也变成了热词...



所以, 和 OpenAPI 有什么差别?



嗯哼? 还以为是对物质世界进行索引, 没想到只是扫描进来再管理...


📆🐍 活动/大会

Events, MeetUp 真的是全球线下活动组织中心


❤️ Happy Pythonic ;-(大妈私人无责任播报)


Happy Pythoning!
