A program/script that returns all the resources called by the URL

So this is more of a "does this sort of thing exist" type of question so please bear with me.

Say I've got a url: https://www.example.com

Now when you load this URL, it may call several javascript files, images, favicons, etc. etc. These can all be viewed in any inspector available in your browser. I would like to retrieve the paths of all the various files (js, json, images, etc.etc.) that are called when I call a given URL and store it somewhere or at least display it together on screen rather than having to open up the inspection menu and copy paste each URL into a file manually.

So my question is, does a program/script exist for this already or would I need to write one? (if I would, it'd probably be in Python).

Many thanks in advance.
