5.3.10. The List Class

A list is a non-sparse sequenced collection similar to the Arrat class (Section 5.3.6, “The Array Class”) to which you can add new items at any position in the sequence. The List creates a new index value whenever an item is added to the list and the associated index value remains valid for that item regardless of other additions or removals. Only indexes the list object generates are valid i.e. the list is never a sparse list and the list object will not modify indexes for items in the list.

Note

The List class also has available class methods that its metaclass, metaclass, the Class class (Section 5.1.2, “The Class Class”), defines. It also inherits methods from the OrderedCollection (Section 5.3.4, “The OrderedCollection Class”) class.
