There's still a NameError to catch if you haven't initialized line:
>>> for line in []:
... break
...
>>> line
Traceback (most recent call last):
File "<stdin>", line 1, in ?
NameError: name 'line' is not defined
I don't much like the break out of a for loop, because it feels like a misuse
of a construct designed for iteration... But take your pick: StopIteration or
NameError. =)
