x = iter(range(5))
y = [0]
try:
zipped = zip(x, y, strict=True)
except ValueError: # assuming that’s the exception you want?
print(next(x))

Should this print 1 or 2 or raise StopIteration or be a don’t-care?

Surely no exception is raised because zip is lazy? Doesn't it still have to be even with strict=True?
