To avoid the ambiguity of `if` after `for` why not follow `for` with `elif`?
for x in ...:

elif break:
# break was called
elif not break:
# looped at least once and break not used
elif pass:
# same as else today
# loop'ed no times
(I always have to think what else means after a for).
Keep thinking... ;)
`else` today /does not/ mean "loop'ed no times". To copy Steven
D'Aprano's example:
py> for x in [1,2]:
... print("inside loop")
... else:
... print("elif never looped")
...
inside loop
inside loop
elif never looped
Mistaking the semantics for "if never looped" is a very common mistake.
