Hi, I'm making an app in Python to interact with the Bookmarks database (adding, removing bookmarks). I have seen that the `moz_places` table requires a GUID and a hash value for the URL. I was looking at the source code but I can't find the definition of the `makeGuid()` function. My intention is to port that code to Python and use that in my app. Can anybody point me to the right direction to accomplish this? Perhaps these functions have been already implemented in Python, if that is the case, do you know where? Is there any other way to generate the GUIDs and Hash values? Any other recommendation? I don't want to build an add-on since the app I'm building is to be used from the console. Thanks!
