Introducing the Python Language Server - Microsoft for Python Developers Blog
Visual Studio has long been recognized for the quality of its IntelliSense (code analysis and suggestions) across all languages, and has had support for Python since 2011. We are pleased to announce that we are going to be making the Python support available to other tools as the Microsoft Python Language Server. It is available first today in the July release of the Python Extension for Visual St
PEP 572 and decision-making in Python
The "PEP 572 mess" was the topic of a 2018 Python Language Summit session led by benevolent dictator for life (BDFL) Guido van Rossum. PEP 572 seeks to add assignment expressions (or "inline assignments") to the language, but it has seen a prolonged discussion over multiple huge threads on the python-dev mailing list—even after multiple rounds on python-ideas. Those threads were often contentious
XARs: An efficient system for self-contained executables – Facebook Code
Distributing large pieces of software to thousands of machines with a wide variety of configurations can pose a significant operational challenge, requiring a process to identify and copy precisely the right combination of dependent libraries and data files for each device. To make this faster, more robust, and more efficient, we have developed and deployed XARs, or eXecutable ARchives, a system f

Python 3の各種エンコーディングについて - Qiita
Python 2 に比べるとずっと楽になったものの、環境によっては Python 3 で予期せぬ UnicodeError に遭遇することがあります。 Python 3.6 時点での、 Python の各種エンコーディングの扱いを整理してみます。 Python のエンコーディング filesystem encoding (sys.getfilesystemencoding()) 主にファイルパスに使うエンコーディングですが、コマンドライン引数にも使われます。 (そうでないとファイルパスをコマンドライン引数に渡したときに困る) また locale が関連するので、実際にはそれ以外にも glibc とかと連携するときに使われます。 Python 2 時代の名残りでしょうが、今では filesystem encoding というより system encoding と呼んだほうが実態を表している

Python Idioms in Rust
I’ve been going through a period of programming language wanderlust over the past couple months. Recently, I’ve been quite interested in Rust. Coming from Python, I’ve found a lot of Rust’s language features to be quite powerful. Earlier this year, I dug deep into Go. For the most part, I enjoy Go: It’s a simple language that can be learned in a few hours (literally). Its structure promotes good p
Breaking a Wine Glass in Python By Detecting the Resonant Frequency
For 50 days straight between January and March of this year, I wrote a creative programming sketch in Python every day. On day six, I tried to write a program to detect the resonant frequency of a glass, and break it. As you can see below, my desktop computer speaker wasn’t quite loud enough to break the glass alone. In today’s post, I walk through the journey of writing a Python program to break
Homebrew の Python で何が変わって何がもとに戻ったのか - methaneのブログ
rcmdnk.com 大分混乱した状態になってしまったので、今年何が変わってきたのか、今回の変更でどこまでもどったのかを整理しておきます。 1/19 python という formula が python コマンドをインストールしなくなりました。 python コマンドを起動すると、通常は /usr/bin/python が起動するようになりました。 1.5.0 — Homebrew 3/2 python という formula が Python 3 になり、 Python 2.7 は python@2 になりました。 python formula (Python 3) が python コマンドをインストールするようになったので、 python コマンドを起動すると通常は Python 3 が起動するようになりました。これが npm の gyp とか色んな所をぶっ壊す変更になっていました
