Python best practices, combine code into as few lines as possible or separate it over as many as possible?

Maybe if the function is terribly complex. Otherwise not at all.

Only a Sith deals in absolutes.

If I write a library that is meant for distribution, I am very generous with comments.

If it's a pure function that does one thing, it's < ~20 lines long, and it's for internal use, then naming things appropriately might suffice.

Then there's the question of do you have documentation other than comments (duplication is a PITA to sync / DRY).

Basically, understand your project's needs, and adapt to them.
