Python in Action: 60 Mini Projects to Automate Everything (Part 2): Practical CLI Tools, File Automation, and Data Cleaning with CSV, Excel, and JSON

By Leo Code

Python in Action: 60 Mini Projects to Automate Everything - Part 2 is where Python goes online.
If Part 1 helped you build solid foundations-project structure, clean CLIs, logging, validation, and real-world data handling-Part 2 (Mini Projects 21-40) teaches you how to work with the outside world: websites that change, services that rate-limit you, flaky connections, inconsistent responses, and data you can't trust until you validate it.
This volume is built for doing, not skimming. Each mini project ends with a practical tool you can reuse: scrapers that export clean datasets, monitors that detect changes, downloaders that save files with sane names, and API clients that behave like professional software.
What you'll build in Part 2
Block 3 - Responsible Web Scraping & Web Automation (21-30)Headline scraper (title/date/link) → CSVPagination scraper that consolidates resultsRate limiting with retries and backoffHTML table extraction and normalizationChange monitor (diff + alerts)Price/stock monitor (report mode)PDF downloader with clean filenamesPage archiver (HTML + metadata + hash)Feed builder (scraping → RSS/JSON)A "polite" scraper: cache, user-agent, basic robots awareness, retries, and logsBlock 4 - APIs: Consume Services Like a Pro (31-40)Simple GET/POST client with consistent error handlingToken authentication + simulated refreshUniversal pagination with generatorsRate limit handler that respects response headersLocal TTL caching to reduce callsOffline mode: fall back to cache when the API failsResponse validation with Pydantic + readable errorsBatch requests with controlled concurrencySync remote data to a local store using upsert logicA mini SDK package with docs, examples, and automated testsWho this book is forPython learners who want real projects, not toy examplesDevelopers who can write scripts but want tools that don't breakAnyone who wants a practical roadmap to web automation and API engineeringIf you want Python to do more than run locally-if you want it to collect, verify, store, and deliver information reliably-Part 2 is your next step.
