<p>I wrote a small Web Application to display data to the user. I want a crawler in the background, fetching all the data (transaction etc) on all addresses. All the user enters is his xpub. I know this is possible but I am a newbie in bitcoin development. So I have zero clue how to achieve this.
The crawler will be written in Python, so if you know a good library to start with, I would be happy to play around.</p>

This question-and-answer website wasn't designed for making software library recommendations so it isn't especially suited to that purpose.

locally generate addresses from the xpub (i hope this is what you mean!) and then just make a request against your bitcoin core instance with txindex enabled (this is gross for user privacy, but so is your entire idea anyway)
