Web Scraping Basics
Web scraping is a method employed to retrieve data and content from web pages, primarily utilizing bots. This technique allows the extraction of either all or specific data, depending on the user’s requirements. Typically, the scraped data is exported in the form of a spreadsheet or an API. The process involves making HTTP requests, performing HTML parsing, and finally, extracting the desired data.
Initiating Your Web Scraping Journey
Several methods can kickstart your venture into web scraping. Utilizing web scraping APIs, libraries, and tools proves to be efficient in this regard, streamlining the web scraping process.
Key Elements of Web Scraping
- HTTPS Requests: Bots acquire web page data through a GET request, but it’s crucial to note that not all websites permit data scraping. The obtained response grants access to the data for scraping.
- Data Extraction from HTML Code: After receiving the HTTP response, data extraction from the HTML code becomes possible. HTML parsing may be necessary, and this can be efficiently achieved using parsing libraries such as Beautiful Soup, xlml, or pyquery.
- Data Storage: Once unstructured data is extracted, it needs to be organized for proper use. Structuring and storing data can be accomplished through CSV or JSON files, making it suitable for various applications. Alternatively, cloud storage infrastructures like AWS S3, Google Cloud, or Fermyon Cloud can be employed for data storage.
