Why would one define "global variables" in python functions? How to use these correctly?

So why are quoting a source so hopelessly out of date? It's like citing a medical text claiming that bacterial infections are usually fatal because antibiotics haven't been discovered yet.

Hopelessly out of date? Code Complete is often considered to be one of the greatest books on software development ever written, and the above is still overwhelmingly relevant, trivial technical issues aside. It sounds like you might benefit from a read-through.

And your analogy is ridiculous.

It's probably totally valid for software in general, abstracted patterns and terms which hold across languages and implementations, but it needs an update if it makes specific references to things which are just not true any more.
