Thanks. :-)

Very nice. I'd have liked this task to allow for larger values of N and K, requiring lists of integers in the output, instead of strings of digits. Then, the same solution would be much less obfuscated.

Yes. More generally, Python needs a grouper function (probably in itertools), similar to Partition in Mathematica (<a href="http://reference.wolfram.com/mathematica/ref/Partition.html">http://reference.wolfram.com/mathematica/ref/Partition.html</a> ).
