I'm having a hard time making this clear. By reading the documentation I 
would guess that "split()" would be equivalent to 
"split(string.whitespace)". In fact they work very differently.

With no separator argument, the separators are grouped. The problem comes 
when your splitted string has multiple separators next to each other. To 
make them work the same is more like this

   mystr.split()
   filter(None, mystr.split(string.whitespace))
