And to pull those two together, I found while-else comprehensible by
analogy with if-else:
while stmt:
do_something() # stmt is True
else:
do_something_else() # stmt is False
I don't think I've ever used a for-else in the wild, but I have used
while-else. And knowing how that works, it's kind of obvious what
for-else does.
