I'm more anti-object than most people, and this doesn't look terrible to me. You have a sequence of imperative steps, and they're represented with two levels of nesting rather than one. So long as nobody fucks the thing up more and overcomplicates your do-nothing automation, even the most vocal opponents of 'class AbstractFoo: pass` are likely to agree that the damage here from that abstraction is minimal.

I don't see any objects in this script though, just functions.

well, he defines a bunch of classes each with a single method then...

just seems to add a lot of abstraction, that might bury your understanding.
