## Resource

In this lesson, you’ll learn about: building scalable scraping systems with Scrapy, mastering selectors in real time, and designing efficient, production-ready spiders1. What is Scrapy (and Why It Matters)?🔹 The Framework ApproachUse Scrapy Not just a library → a full scraping engine Handles: Requests scheduling Data pipelines Middleware Concurrency 👉 Key Insight Scrapy follows the Hollywood Principle:“Don’t call us, we’ll call you” You define rules → Scrapy controls execution2. Project Setup with Scrapy CLI🔹 Initialize a Projectscrapy startproject myproject cd myproject scrapy genspider example example.com 🔹 Project Structure Overview spiders/ → your scraping logic items.py → data models pipelines.py → cleaning & storage settings.py → configuration 👉 Clean structure = scalable scraping system3. Mastering the Scrapy Shell🔹 Interactive Testing Toolscrapy shell "https://example.com" 🔹 Why It’s Powerful Test CSS selectors instantly Test XPath queries in real time Debug without running full spiders 🔹 Handling 403 Forbidden ErrorsWebsites may block bots → fix using User-Agentscrapy shell -s USER_AGENT="Mozilla/5.0" "https://example.com" 👉 Key Insight Many blocks are superficial → mimic real browser behavior4. Building a Professional Spider🔹 Basic Spider Structureimport scrapy class ExampleSpider(scrapy.Spider): name = "example" def start_requests(self): urls = ["https://example.com"] for url in urls: yield scrapy.Request(url=url, callback=self.parse) def parse(self, response): for item in response.css("div.item"): yield { "title": item.css("h2::text").get(), "link": item.css("a::attr(href)").get() } 🔹 Key Concepts1. Inheritance Spider inherits from scrapy.Spider Gains built-in crawling behavior 2. start_requests Entry point of the spider Sends initial HTTP requests 3. p…
