Web Crawl with out not getting your ip Blocked :P

I have had this data science project on my way where i had to crawl data from websites like amazon. Its fairly predictable that your IP might get blocked when the website detects your web-crawl pattern.

Here is the what i had to did. I took a bunch of proxies available for free ( few premium options available too) and make a random choice each time when you hit the url.

Pretty simple!!
