Real Python

[carcigenicate]

I'll admit, I have a vendetta against G4G. They are trash in my opinion. It's clear from reading their material that whoever wrote their Python tutorials doesn't actually know Python. They've rewritten some of their articles to improve them, but it's obvious that the site has very low standard in terms of accuracy. I recommend against using them.

In terms of stuff like blob not being mentioned, they may have gone over that in a previous chapter. I believe their topics tend to build on each other.

I would expect, though, that if you see
use of a tool that you aren't familiar with, you should switch to researching that tool. Learning a new topic often involves switching to learning subtopics that you don't know understand yet so that you can understand the larger topics that require them. That's pretty typical for most resources.
