This is not a bug, it's the author failing to understand Python's syntax for chained comparisons:

  a is b is c

is equivalent to

  (a is b) and (b is c)

I use this syntax most often with a < b < c to check that all items are in the expected order.

Thank you for the explanation, I really appreciate it. I've updated the article to more accurately reflect what goes on under the hood.

Is there a way to edit submission titles? Or is that a moderator only thing?

It's a surprise to me that like "==" or "<", the "is" comparison operator can be chained. TIL. The author is a bit hyperbolic though.
