Web scraper for Vendr.com according to the next task:

• Collect all products from the website https://www.vendr.com/ :
• Collect products from only three categories: DevOps, IT Infrastructure, Data Analytics and Management
• The following data should be collected: product name, category, price range, and description (refer to the attached photo).
• The scraping must be implemented with requests for fetching data and lxml for parsing.
• Implement a task queue specifically for managing the product scraping tasks. Each thread should take a task (i.e., a product to scrape) from the queue and process it.
• Use multithreading in your implementation, with multiple threads fetching product data from the queue and one dedicated thread writing the collected data to the database in parallel.
• Ensure that all scraping results are stored in the database.
