| 2. What is the role of back-end programming in web scraping? | |
Ans. Back-end programming plays a crucial role in web scraping as it involves writing code to send HTTP requests, handle responses, parse HTML/XML content, and extract data. In the context of Scrapy, back-end programming is used to define the spider, which is responsible for navigating websites, extracting data, and storing it in a structured format.
| 3. Can web scraping be used for legal purposes? | |
Ans. Yes, web scraping can be used for legal purposes as long as it adheres to the website's terms of service and respects the legal boundaries set by the website owner. It is important to ensure that the scraping process does not cause any harm or disrupt the website's normal functioning.
| 4. Are there any ethical considerations to keep in mind while web scraping? | |
Ans. Yes, there are ethical considerations to keep in mind while web scraping. It is important to respect the website's terms of service, avoid scraping sensitive or personal data without consent, and not overload the website's server with excessive requests. Additionally, it is recommended to use web scraping responsibly and for legitimate purposes.
| 5. What are the common challenges faced in web scraping? | |
Ans. Some common challenges faced in web scraping include handling dynamic content that requires JavaScript execution, dealing with anti-scraping measures implemented by websites, maintaining consistent data extraction in the face of website changes, and managing large amounts of scraped data efficiently. It is important to be aware of these challenges and use appropriate techniques to overcome them.
