Technologies used for web-scraping

[jasmineyang]

We want a simple beginner's tutorial to have the installation steps for basic technologies used for web-scraping. The goal is that students can become acquainted with these tools (e.g. beautifulsoup, Scrapy) by just following the exact steps, and then later on we may use examples (#70) to demonstrate the technologies.

List of topics in order:

• Introduction to web-scraping: What it is and why is it useful
• BeautifulSoup: Installation, Expressions & Examples (eg. extracting needed information from HTMP pages)
• Manually scape data using browser extensions
• Scrapy: Installation, Rules & Examples (eg. writing a simple scraper, telling Scrapy to follow URLs and scrape contents)
  and more.
