Pythonプロジェクトでflat layoutではなくsrc layoutが推奨される理由を理解する - 肉球でキーボード
本文中コード github.com flat layoutとsrc layoutについて Pythonプロジェクトのディレクトリ構成について調べてたところ、flat layoutとsrc layoutという2種類のディレクトリ構成が存在することを知りました。 src レイアウト対フラットレイアウト - Python Packaging User Guide flat layout flat layoutはパッケージフォルダをプロジェクトのルート直下に配置するスタイルです。 flat layoutの有名なpythonプロジェクトだと、 pytorch, django, tensorflow があります。 . ├── README.md ├── pyproject.toml └── my_package/ ├── __init__.py └── module.py src layout 一方、

uv一つでPythonプロジェクトのランタイム･パッケージ管理が完結。pip/poetry/pyenv/virtualenvをまるっと置き換え! | DevelopersIO
Pythonのリンター･コード整形ツール Ruff を開発している Astral から、Pythonのパッケージツール uv の大型アップデート(uv v0.3)の知らせが届きました。 発表されたブログには「uv: Unified Python packaging(訳:統一されたPythonパッケージング)」とあり、READMEには以下の一文があります。 A single tool to replace pip, pip-tools, pipx, poetry, pyenv, virtualenv, and more. https://astral.sh/blog/uv-unified-python-packaging プロジェクトのランタイムのバージョン管理(pyenv/.python-version)、プロジェクト固有の環境(virtualenv)、パッケージ管理(pip/poetry
それぞれのツールに関する詳しい説明は本記事では行いません。詳しく知りたい方は、ツール名のリンクから公式ドキュメント等を参照してみてください。 上記の表に挙げたツール群にはそれぞれに特徴があります。pyenv、venv、pipのように単一機能に特化したものから、Condaのようにデータサイエンスや機械学習プロジェクトで使用される複雑なパッケージの依存関係や環境管理をサポートするツール、PoetryのようにPythonパッケージインデックス（PyPI）への公開をサポートするツールなど、開発シーンに合わせて選択することができます。 uvとは uvは2024年の2月中旬に発表されたばかりの新しいパッケージ管理ツールです。Rustで書かれており、ここ最近で飛躍的に使用されるようになったRust製のPythonリンター＆フォーマッター「Ruff」を開発しているAstral社によって提供されています[1
How uv got so fast
uv installs packages faster than pip by an order of magnitude. The usual explanation is “it’s written in Rust.” That’s true, but it doesn’t explain much. Plenty of tools are written in Rust without being notably fast. The interesting question is what design decisions made the difference. Charlie Marsh’s Jane Street talk and a Xebia engineering deep-dive cover the technical details well. The intere
This all started with a blog post back in 2020, from a tech curiosity: what's the fastest way to scale containers on AWS? Is ECS faster than EKS? What about Fargate? Is there a difference between ECS on Fargate and EKS on Fargate? I had to know this to build better architectures for my clients. In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t
そのPythonパッケージ管理、venv + pipでよくないですか? in 2023/1 各所(主にPython界隈の外)で「Pythonパッケージ管理どうするのが正解なの?」とよく耳にするので2023年初頭時点での私の見解を書きます。 tl;dr 多くの場合のPythonパッケージ管理はvenv(virtualenv) + pipで済むのでは? 前提 タイトルにvenvとついていますが、以降venv(virtualenv)については言及しません。仮想環境内で作業している前提で話を進めます。 この記事では基本的にsetup.py / setup.cfgではなくpyproject.tomlでのパッケージ定義方法を採用します。これはPEP 621がここ最近で採択・実装されたためです。 なお、想定しているPythonや各ツールのバージョンは以下の通りです。 Python >= 3.8 pip

For this release, we focused on bui
There are lots of posts trying to show how simple it is to get started with Kubernetes. But many of these posts use complicated Kubernetes jargon for that, so even those with some prior server-side knowledge might be bewildered. Let me try something different here. Instead of explaining one unfamiliar matter (how to run a web service in Kubernetes?) with another (you just need a manifest, with thr
Photo by Claudio Schwarz on Unsplash. How to create a Python package? In order to create a Python package, you need to write the code that implements the functionality you want to put in your package, and then you need to publish it to PyPI. That is the bare minimum. Nowadays, you can also set up a variety of other things to make your life easier down the road: continuous testing of your package;

開発品質とDeveloper eXperienceを高めるコンテナ開発環境のご紹介 (Python) - ABEJA Tech Blog
はじめに こんにちは 2023年1月に入社し、システム開発グループでエンジニアをしてる春名です。 私の所属しているシステム開発グループでは、開発初期の環境構築をより効率的に行うための活動に取り組んでいます。 今回はそのうちの一つである、Pythonでコンテナ開発をする環境を構築した内容をご紹介します。 なぜコンテナ開発環境かと言いますと、単にAWSのECSやGoogle CloudのCloud Runを使ってデリバリーする案件が多いからです。 より使用頻度の高い開発環境を整備し、テンプレート化しておくことで開発の効率化に活用しています。 2025/12/19 追記 最新のPython開発環境を以下の記事でご紹介しています！ tech-blog.abeja.asia 本記事の内容もご参考にいただきつつ、最新の情報をご確認ください🚀 目次 はじめに 目次 今回作成する環境 Poetryによる

There has been one thing that I have not publicly shared before and that is that ever since Rye exists I have also been talking to Charlie Marsh about Python packaging and Python tooling. It turns out that we had some shared ideas of what an ideal Python tooling landscape would look like. That has lead

There is an area of Python that many developers have problems with. This is an area that has seen many different solutions pop up over the years, with many different opinions, wars, and attempts to solve it. Many have complained about the packaging ecosystem and tools making their lives harder. Many beginners are confused about virtual environments. But does it have to be this way? Are the current

Astral builds tools that millions of developers around the world depend on and trust. That trust includes confidence in our security posture: developers reasonably expect that our tools (and the processes that build, test, and release them) are secure.

Rye: A Vision Continued
written on February 04, 2024 In April of last year I released Rye to the public. Rye, both then and now, represents my very personal vision of what an improved Python packaging and project management solution can look like. Essentially, it’s a comprehensive user experience, designed so that the only tool a Python programmer would need to interface with is Rye itself and it gets you from zero to on
I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a
