This can be shortened to
def interlace(x, i):
"""interlace(x, i) -> i0, x, i1, x, ..., x, iN
"""
i = iter(i)
i.next()
for e in i:
yield x
yield e
I have noticed a while ago that inside generators StopIteration is
automatically trapped, i.e.
def g():
yield 1
raise StopIteration
yield "Never reached"
only yields 1. Not sure if this is documented behavior, however, of if
it is an implementation
accident. Anybody who knows?
