Not sure what you mean here. If you have a try-finally with no except
clause, no exceptions will be caught; the try will be run, then the
finally, and then you'll s
Hmm, ok, I can work with that :)
If I were writing Python right now, I would argue that if you're going to
build this try/except/else/finally construct, each of the three result
clauses represent potential outcomes. The fail case, the success case, and
the no-matter-what case. And then, you should

A better question is: "Is there a reason why else without except
should be valid syntax?"

Adding features to the language always has a cost in that it slightly
complicates the language and makes it harder to teach. Because of that the bar
for adding features is high.

Reading on mobile I missed that you were referencing Celelibi's answer and
not the thread generally [facepalm]. My apologies for that.
I've been previously bitten (multiple times) by code where a developer has
used a try/except to catch errors from one of several actions in a try
block, but a bug
Is this a relevant argument (either way) here?
While I appreciate considering the applicability of the argument to
existing code is generally a good thing, I'm not sure that it makes sense
for cases like this where a logical outcome seems to be missing. If you can
