That change is about True and False, not true and false. If OP was thinking of the former pair, it would seem my “different identifiers” guess was correct.

Python doesn’t have true or false keywords, nor any other primitives by those names.

So either you’re thinking of a different language, or different identifiers, or someone assigned equal values to variables with those names and then blogged about it.

It’s refreshing to see someone on social media who doesn’t dismiss code as “outdated” just because of its age.
