The only thing that isn’t perfectly straightforward is “what is __name__”, but once you know how __name__ is defined…
OTOH, that example is much more complicated than needed.
As a simple executable script, that would do the same thing if antigravity. Fly() actually did anything, all that is needed is:
import antigravity
antigravity.fly()
The rest is unnecessary boilerplate to provide a module that can operate either as a library or a script, which is superfluous here. Moreover, since the actual functionality it is demonstrating is all in an import hook, all you actually need (the rest just produces an error message) is:
