The nearest posts are ../python-duckdb/ for SQL analytics, ../python-polars/ for DataFrame expressions, ../python-pyarrow/ for Arrow/Parquet exchange, and ../streamlit-data-editor-workflow/ for editable UI validation. This article instead focuses on Python's standard-library csv parser and writer: quoting/newline rules, DictReader/DictWriter, dialects, schema checks, encoding, and constant-memory row cleanup. source check: Reviewed against the current official Python 3.14 csv documentation on 2026-09-07, including newline handling, DictReader/DictWriter, Dialect, Sniffer, line_num, strict parsing, and writer conversion behavior. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> https://dailypypy.org/learn/sklearn-pipeline-columntransformer/ Sun, 06 Sep 2026 11:08:00 +0800 https://dailypypy.org/learn/sklearn-pipeline-columntransformer/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, bust shot, front-facing eye-level view, arms crossed, confident gentle smile, looking at viewer, pale peach background, subtle floating connected blank geometric blocks and soft branching pathways without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: The 155-post inventory contains no scikit-learn tutorial. The nearest item, ../python-uv/, only names scikit-learn in an installation example and does not discuss estimators, preprocessing, Pipeline, ColumnTransformer, cross-validation, or leakage.

The general inference post only trims recent turns, the server post covers HTTP-level automatic prefix caching, and the quantization post compares model-weight artifacts with one KV-memory reminder. This article instead builds an end-to-end token budget, explains prefill versus decode memory, estimates KV size, compares prefill chunking, rotating cache, KV-cache quantization, and reusable on-disk prompt caches, then defines a long-context benchmark matrix. It does not repeat model installation basics, server deployment, tool calling, weight conversion, or general batch inference. source check: Reviewed against the current official MLX-LM README, generate.py, cache implementation, multi-turn prompt-cache example, and the selected model config on 2026-09-05. The current CLI exposes max-kv-size, prefill-step-size, prompt-cache-file, kv-bits, kv-group-size, and quantized-kv-start; model/cache compatibility still needs measurement instead of assumption. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> https://dailypypy.org/learn/numpy-broadcasting-indexing/ Fri, 04 Sep 2026 10:27:00 +0800 https://dailypypy.org/learn/numpy-broadcasting-indexing/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, from below low angle, full body, balancing on one foot while arranging three floating blank translucent array blocks with both hands, delighted eureka expression, looking at viewer, pastel aqua background, subtle floating aligned grid cells and soft singleton-axis ribbons without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: The current inventory has no NumPy fundamentals article. ../python-pytorch-nn/ only introduces tensors and reshape, ../python-mlx/ compares MLX arrays with NumPy at a high level, and ../python-numerical-integral/ uses NumPy for numerical integration. This article instead teaches ndarray shape reasoning, basic versus advanced indexing, boolean masks, broadcasting rules, singleton axes, keepdims, and systematic shape-error debugging. source check: Reviewed against the current official NumPy user guide on 2026-09-04, especially the broadcasting, indexing, expand_dims, copies/views, and ufunc documentation. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> https://dailypypy.org/learn/github-pull-request-review/ Thu, 03 Sep 2026 12:44:00 +0800 https://dailypypy.org/learn/github-pull-request-review/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, close-up, face focus, three-quarter view, making a peace sign beside her cheek with one hand and holding a small blank translucent review card with the other, playful confident wink, looking at viewer, pastel coral cream background, subtle floating connected blank cards and soft green approval dots without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: This article focuses on the GitHub pull-request collaboration lifecycle: Draft state, review-ready criteria, description contracts, review decisions and conversations, required checks, merge readiness, auto-merge, and post-merge cleanup. ../git-branch-strategy/ teaches branch models and gives only a high-level PR policy and merge-method overview; ../git-worktree/ teaches an isolated local workspace for checking out a PR; ../gh-cli/ is a general GitHub CLI introduction; the GitHub Actions articles build CI workflows. This article cross-links those posts and does not repeat their branch, worktree, or workflow configuration tutorials. source check: Reviewed against current official GitHub documentation on 2026-09-03 for Draft PR behavior, review decisions, required reviews and status checks, merge methods, auto-merge, and automatic head-branch deletion.

Existing uv posts cover general package management, project/workspace lockfiles, uv.lock-based CI, PEP 723 scripts, package publishing, and interpreter management. This article focuses on migrating legacy `requirements.in` / `requirements.txt` / pip-tools deployment flows to `uv pip compile`, including constraints, hashes, Docker, generated-file checks, and rollback. It intentionally preserves requirements-format outputs and does not repeat the broader uv project workflow. source check: Reviewed against the current Astral uv pip compile, Docker, and GitHub Actions documentation on 2026-09-02; examples use setup-uv v10-era syntax and distinguish `uv pip install` from exact-environment `uv pip sync`. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> 有些 Python 專案不是從 <code>pyproject.toml</code> 開始長大的。 它們可能只有幾個檔案：</p> https://dailypypy.org/learn/pandas-groupby-pivot-report/ Tue, 01 Sep 2026 11:53:00 +0800 https://dailypypy.org/learn/pandas-groupby-pivot-report/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, side profile, wide shot, full body, walking between three soft translucent blank report panels, hands behind back, pleased analytical smile, looking over shoulder at viewer, pastel seafoam green background, subtle floating blank table cells and rounded chart blocks without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature ---> <h2 class="relative group">一. 前言：資料很多，不代表報表就有答案 <div id="一-前言資料很多不代表報表就有答案" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 ltr:-left-6 rtl:-right-6 not-prose group-hover:opacity-100"> <a class="group-hover:text-primary-300 dark:group-hover:text-neutral-700" style="text-decoration-line: none !important;" href="#%e4%b8%80-%e5%89%8d%e8%a8%80%e8%b3%87%e6%96%99%e5%be%88%e5%a4%9a%e4%b8%8d%e4%bb%a3%e8%a1%a8%e5%a0%b1%e8%a1%a8%e5%b0%b1%e6%9c%89%e7%ad%94%e6%a1%88" aria-label="定位點">#</a> </span> </h2> <p>拍拍君每次拿到銷售明細，最常看到的問題不是「怎麼讀 CSV」， 而是讀完之後，大家開始手動複製、貼上、加總，再做一張新的 Excel。</p> https://dailypypy.org/learn/streamlit-data-editor-workflow/ Mon, 31 Aug 2026 10:55:00 +0800 https://dailypypy.org/learn/streamlit-data-editor-workflow/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, dutch angle, full body, three-quarter view, kneeling beside a low translucent blank grid, one hand carefully adjusting a small blank tile, focused playful smile, looking at viewer, pastel blush rose background, subtle floating blank spreadsheet cells and soft rounded upload tray shapes without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: Rescued planned draft on 2026-08-31 after a current-source inventory scan.

This article is distinct because it focuses on the `st.data_editor` editable DataFrame workflow: upload validation, typed columns, row-level error reporting, controlled edits, and CSV export from edited data. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> https://dailypypy.org/learn/streamlit-fragments-dialogs/ Sun, 30 Aug 2026 12:55:00 +0800 https://dailypypy.org/learn/streamlit-fragments-dialogs/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, from below low angle, cowboy shot, three-quarter view, standing while opening a small blank translucent floating panel with one hand and making a gentle pause gesture with the other, clever gentle smile, looking at viewer, pale lavender background, subtle floating separated interface cards and soft circular ripple shapes without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: This is an execution-flow-specific follow-up to ../python-streamlit-advanced/ and ../streamlit-apptest-pytest/. The advanced article explains full-app reruns, Session State, cache, forms, and multipage structure; the testing article uses AppTest to trigger and assert reruns. This article focuses on independent @st.fragment execution, run_every live panels, fragment/app rerun boundaries, @st.dialog modal workflows, dismissal behavior, and idempotent side effects. It also differs from ../streamlit-sqlmodel-crud/, which builds CRUD persistence and only treats rerun as an implementation caveat. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> https://dailypypy.org/learn/git-rerere/ Sat, 29 Aug 2026 10:44:00 +0800 https://dailypypy.org/learn/git-rerere/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, eye-level medium shot, upper body, three-quarter front view, arms folded comfortably, confident knowing smile, looking at viewer, pastel lemon cream background, subtle paired looped ribbons and interlocking translucent geometric shapes without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: This is a conflict-resolution-reuse follow-up to ../git-rebase/. The older article teaches history rewriting, interactive rebase, and resolving one conflict safely; this article focuses on rerere's local resolution cache, repeated merge/rebase conflicts, inspection commands, autoupdate policy, invalidating stale records, retention, and team guardrails. It also differs from ../git-reflog/, which recovers commits and references after history-changing operations rather than remembering file-level conflict resolutions. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p> <h2 class="relative group">一. 前言：同一個衝突，為什麼要解第二次？ <div id="一-前言同一個衝突為什麼要解第二次" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 ltr:-left-6 rtl:-right-6 not-prose group-hover:opacity-100"> <a class="group-hover:text-primary-300 dark:group-hover:text-neutral-700" style="text-decoration-line: none !important;" href="#%e4%b8%80-%e5%89%8d%e8%a8%80%e5%90%8c%e4%b8%80%e5%80%8b%e8%a1%9d%e7%aa%81%e7%82%ba%e4%bb%80%e9%ba%bc%e8%a6%81%e8%a7%a3%e7%ac%ac%e4%ba%8c%e6%ac%a1" aria-label="定位點">#</a> </span> </h2> <p>你在功能分支上埋頭開發兩週，每天都把最新的 <code>main</code> rebase 進來。 偏偏團隊也在改同一份設定檔，於是那三行衝突像固定打卡一樣，每隔幾天就回來一次。 第一次仔細判斷、跑測試、完成解法很合理；第五次還靠記憶重打一遍，就只是把腦力浪費在重播。 Git 其實內建了一個低調工具：<code>rerere</code>，名稱來自 <strong>reuse recorded resolution</strong>。 它會記住「某種衝突長什麼樣」以及「你最後怎麼解」，下次遇到相同或可套用的衝突時，把舊解法放回工作樹。 這篇拍拍君會帶你完成一條可重做、可檢查的流程：</p> <ul> <li>在單一 repo 或全域啟用 rerere；</li> <li>製造並手動解掉第一次衝突；</li> <li>重跑 merge，觀察舊解法自動出現；</li> <li>用 <code>status</code>、<code>remaining</code>、<code>diff</code> 檢查紀錄；</li> <li>撤銷錯誤記憶，管理保留期限；</li> <li>把 rerere 放進 rebase 與團隊工作流程，又不跳過 review。 如果你還不熟悉 rebase 本身，先看 <a href="../git-rebase/">Git rebase 完全攻略</a>；如果是不小心把 commit 弄丟，該找的是 <a href="../git-reflog/">Git reflog 救援實戰</a>。</li> </ul> https://dailypypy.org/learn/duckdb-remote-parquet-s3/ Fri, 28 Aug 2026 10:47:00 +0800 https://dailypypy.org/learn/duckdb-remote-parquet-s3/ <!--- 1440x768 prompt: masterpiece, best quality, highres, clean anime illustration, japanese anime style, soft shading, flat color design, 1girl, black hair, green eyes, white off-shoulder shirt, black short skirt, from above, full body, crouching beside a small blank translucent data cube, one hand pointing toward layered floating storage shapes, bright curious smile, looking up at viewer, pastel periwinkle blue background, subtle floating translucent file blocks and cloud arcs without symbols or text, neat composition, detailed eyes, cute and smart vibe, minimal background, polished illustration, no text negative prompt: worst quality, bad eye, bad hand, extra limbs, manga, multiple views, monochrome, text, signature dedup note: This remote-object-storage article is a focused follow-up to ../python-duckdb/, which teaches local CSV/Parquet querying and basic SQL. It differs from ../python-fsspec/ by using DuckDB httpfs and typed Secrets rather than a general filesystem abstraction, and from ../python-pyarrow/ by focusing on remote range reads, object-store globbing, Hive partition pruning, projection/filter pushdown, and request diagnostics rather than Arrow schemas and dataset exchange.
