1. What is Web Scraping? Web scraping is the process of extracting data from websites. It involves sending HTTP requests to a website, parsing the HTML content, and then extracting the desired information. Python is a popular choice for web scraping due to its versatility and the availability of powerful libraries.

2. Libraries for Web Scraping in Python In Python Training, students are often introduced to various libraries for web scraping, such as:

• Beautiful Soup: A library for parsing HTML and XML documents, making it easy to extract data.
• Requests: A library for sending HTTP requests, which is essential for fetching web pages.
• Scrapy: A powerful and highly customizable web scraping framework.
• Selenium: Ideal for scraping dynamic web pages, as it can interact with websites like a real user.

3. The Web Scraping Process a. Sending HTTP Requests

• In Python, you can use the requests library to send GET or POST requests to a website's URL.
• You'll receive the web page's content as an HTTP response.

b. Parsing HTML Content

• Beautiful Soup helps parse the HTML content by creating a parse tree, making it easier to navigate through the document.

c. Extracting Data

• Use Beautiful Soup to extract data from the parsed HTML, often by selecting specific HTML elements using tags, classes, or attributes.

4. Common Challenges in Web Scraping Web scraping can be challenging due to the dynamic nature of websites and the need for error handling. In Python Training, students learn to overcome common challenges, including:
