Act as a senior Python developer with 5+ years of experience in web scraping. Teach me how to scrape data from a website using Python and BeautifulSoup. Include the following steps: 1) Installing required libraries ([LIBRARY_NAME]), 2) Fetching HTML content from a target URL ([TARGET_URL]), 3) Parsing the HTML using BeautifulSoup ([PARSER_TYPE]), and 4) Extracting specific data (e.g., titles, links) using CSS selectors or other methods. Provide a complete, runnable code example and explain best practices for handling common issues like dynamic content, rate limiting, and ethical considerations. Make sure the tutorial is beginner-friendly but also covers advanced techniques for efficient scraping.
