Step 1: scrape the price

🌐 English · Dansk · Bahasa Melayu

Assignment. Use BeautifulSoup to get the price of the Instant Pot on the practice page as a floating point number and print it.

What we built. get_title(html) and get_price(html) in infrastructure/scraper.py. The price is in the first element with class a-offscreen; its text is $99.99. split("$") drops the currency sign and float() makes the number.

The practice page

The bot prints the title and the price

What we gained

  • How to find an element in the browser's inspector and select it with BeautifulSoup (select_one).
  • How to clean scraped text (strip, split) before converting it with float().
  • Tests that use a saved copy of the page, so they run without the network.
  • A clear error (PriceNotFoundError) when the element is missing.
