I'll add a couple more suggestions:
1. Delay the test for maxsplit, as str.split() does the right thing if
maxsplit is None.
2. Use a generator to pad the list, to avoid interim list creation. This
works fine, because list.extend() accepts any iterable. This also shortens
the code a bit, because xrange() does the right thing in this case with
negative numbers. For example:
def nsplit(s, delim=None, maxsplit=None):
results = s.split(delim, maxsplit)
if maxsplit is not None:
results.extend('' for i in xrange(maxsplit - len(results)))
return results
