About the Book
This book is a hands-on technical guide to building a practical 'Flea Market Price Tracker' from scratch using `DrissionPage`, a modern automation library for Python.
The goal is to master practical web scraping skills by leveraging the full power of `DrissionPage`, which combines the strengths of Selenium and Requests.
The content provides a systematic walkthrough of a professional development workflow, starting with basic data scraping and progressing to comprehensive multi-page information gathering, performance optimization via `WebPage` and `SessionPage` integration, data persistence with `pandas`, and refactoring code into classes.
The final chapter details how to schedule the completed tool using standard OS features to create an autonomous data collection platform.
By completing this book, readers will acquire the knowledge and techniques not just to write a simple script, but to design and develop efficient, maintainable automation tools.
