A Zillow scraper, and the tutorial written around it
A publisher of scraping tutorials needed working code that doubled as teaching material. We wrote a commented Zillow scraper with incremental CSV output and the article that walks a beginner through its design decisions.
Developer education. Data.
A commented Zillow scraper, and the article that teaches it
Screens from this system are being added.
The situation
The publisher needed working code that doubled as teaching material: a scraper its readers could run, read line by line and extend, and an article that explained the choices rather than just the steps.
What we built
- A Python scraper for Zillow listings, commented at the level a reader learning the craft can follow
- Incremental CSV output, so a long run keeps what it has already collected
- A tutorial article written for beginner and intermediate developers, structured around the scraper's design decisions
- Delivered as one fixed-scope milestone, opened on 22 October and accepted on 8 November 2023
What changed
The publisher had a scraper and an article that matched each other, ready to run and ready to publish.
