“Python dominates as the de facto platform for new technologies” and “Learn Python. That’s the biggest takeaway we can give you from its continued dominance of IEEE Spectrum’s annual interactive rankings of the top programming languages. You don’t have to become a dyed-in-the-wool Pythonista, but learning the language well enough to use one of the vast number of libraries written for it is probably worth your time.”

“Skybison is experimental performance-oriented greenfield implementation of Python 3.8. It contains a number of performance optimizations, including: small objects; a moving GC; hidden classes; bytecode inline caching; type-specialized bytecode; an experimental template JIT.”

In this tutorial, you’ll learn about optional arguments in Python and how to define functions with default values. You’ll also learn how to create functions that accept any number of arguments using args and kwargs.




On UNIX-like operating systems you can have the Python equivalent of node_modules today, for every Python version, without changing your workflows.

Pick up the awesome programming potential of Python with software like Mastering PyCharm (2021 Edition) & Object-Oriented Programming (OOP) in Python. Pay what you want & support charity!

The PyCon US organizers are looking for motivated volunteers who want to contribute their time and knowledge to make this year’s conference a great success.

Andrej Karpathy (Director of AI at Tesla) shares an interesting performance observation on this Twitter thread that turns into a tale about accurate benchmarking. Calculating math.sqrt(1337.0) appears to be 10x faster than numpy.sqrt(1337.0). Python’s built-in square root (x ** 0.5) appears to be even faster. However, most of the performance differences seem to come from the benchmark setup, as Ishan Bhatt explains in this writeup.


Articles, Tutorials and Talks

A break down of what Apple Silicon means for Python users today, especially those doing scientific computing and data science: what works, what doesn’t, and where this might be going.

“This is the fourth article in a series about writing my own SQL query builder. Today, we’ll rewrite it from scratch, explore API design, learn when to be lazy, and look at worse and better ways of doing things – all in 150 lines of Python!”

Learn why it’s important to split your dataset in supervised machine learning and how to do that with train_test_split() from the widely used scikit-learn package.




Can you make a version of Python that fits within the memory constraints of a microcontroller and have it still feel like Python? That is the intention behind CircuitPython. This week on the show, Scott Shawcroft, who is the project lead for CircuitPython.




“We present and compare all possible alternatives you can use to parse languages in Python. From libraries to parser generators, we present all options.”


用 Python 编译一切语言,


Caching in Django can be implemented on different levels (or parts of the site). This article looks at how to use the low-level cache API in Django.


从根儿上缓存 Django 的一切?


“The async/await pattern can be explained in a simple manner if you start from the ground up. And that’s what we’re going to do today.”

How to use ctypes to run SQLite queries without using the built-in sqlite3 Python package, and without compiling anything.



for row in query('my.db', 'SELECT * FROM my_table WHERE a = ?;', ('b',)):

成果就是可以直接用 SQL 了...



叕一个音频模拟项目, 用 Python 在内存中复活前苏联独有电子变音器吧



Interesting Projects, Tools and Libraries, Projects & Code


嗯哼? 专用键盘驱动? Python 这么任性的?



也就是说, 可以直接用 Py 来自动生成 Go 代码了, 等等, Py 本身内置 AST 为什么没有 Golang 来解析 Py 代码自动生成?




叕一个薅NASA 经验的项目, 不过, 这都是60年前的数据了, 要不是 天宫 发射成功, 照样不会公开...



FastAPI 团队作品, 基于 SQLAlchemy 给出更加 Pythonic 的 SQL 使用形式.
