That's probably not the best way.
list(itertools.chain.from_iterable(zip(itertools.repeat("insertme"), [1, 2,
> 3])))
(tested)
written like this:
inserts = itertools.repeat("insertme")
itertools.chain.from_iterable(zip(inserts, x))
(untested)
But it's not far. I wouldn't use Ian Kelly's method (no offence), because
of len(x): it's less compatible with iterables. Others have ninja'd me with
good comments, too.
