The usual answer is an array of a single empty string, but I've never liked this and prefer the empty array.
Python naturally does both, as this is the most confusing behaviour possible. It only makes sense in Sanskrit, under particular phases of the moon. If you specify the toke, it returns an array of one empty string. If you _don't_ specify the token, then it does "default-based splitting" and looks for a normalised sequence of a set of the usual whitespace characters. BUT it also changes its empty string behavour so that it then returns an empty array instead!
