The confusion, as you can see from other posts, is because the
behavior is different from default split().
Default split works on whitespace and we don't get leading/trailing
empty list items.
So just add input = input.strip('2') after the input assignment (BTW
someone had
pointed input is a reserved identifier). Note this solution will work
for splitting on any sequence of chars..just strip them first. Note we
still get empty elements in the middle of the string -- this probably
we want to get in most cases.
