You can include one starred name among the names to unpack into. Python will fill in all the others based on position, and then stuff the rest into the starred name.
In this case, I use _ for the name, because I really only intend to throw those away. _ is a completely valid name in Python, but it's conventionally used as a "throw away" name. If you're curious, you can still see what was parked in there in the above code with...
P.S. Bit of shameless self-promotion, all of the above is in my forthcoming book "Dead Simple Python" (No Starch Press, 2021). So, it isn't quite that "no one" covers this stuff.

That's exactly why I said the unpack operator deserves an isolated article.
BTW, I'd be glad to read your book.
If you want, you can add directly here the link 😉
