Description:
 def _reset(self, load):
 """ Reset sorted list load. The *load* specifies the load-factor of the list. The default load factor of '1000' works well for lists from tens to tens of millions of elements. Good practice is to use a value that is the cube root of the list size. With billions of elements, the best load factor depends on your usage. It's best to leave the load factor at the default until you start benchmarking. """
