While not especially ingenious, this method does modify the list in
place, and is different.  Well, only in the sense that it is basically
the equivelent inverse of what you did. ;-)

def remove_false_from_list(the_list):
   for item in the_list:
      if not item:
         the_list.remove(item)
   return the_list
