Barcode Price Scraper

Barcode Price Scraper This project is pretty straight forward, I need a web scraper to scrape the prices from 3 different sites by a given barcode, so basically it is 3 different "machines" The sites are: [login to view URL] [login to view URL] [login to view URL] From a given list of barcodes each site will be posted the barcode and the price and game title extracted. For example, entering 5026555258043 will result in The Simpsons: Hit & Run (£2.24) The name of the game and price will be saved separately, the final result of the scraping will be a JSON file with the following structure: [ { "title": "The Simpsons: Hit & Run", "price": "2.24", "currency": "£" } ] When scraping the sites there should be possible to add a delay between each request (it will sleep for x seconds after posting the next barcoe) If a site does not respond (refuses connection) which can happen due to scraping preventions) the scraper shall pause for (x) seconds and re-try, it shall re-try for (y) times, increasing the delay by (x) for each attempt, if the site has not responded after 3 attempts, it will halt and save it´s state so that the next time it is run it will start from the previous position in the list. Example: The connection is refused so the scraper pauses for 3 minutes and then retries, if that request also fails if will pause for 6 minutes, last retry 12 minutes and then fail. Here is a list of sample barcodes: 3307215804377 5030933121638 3307216029557 5030917197116 5030917215094 5026555258043 5030930045586 5060004762255 5026555300490 3348542180628
