sorting - Is there a standard Python data structure that keeps …
网页Cheap searching and cheap insertion tend to be at odds. You could use a linked list for the data structure. Then searching to find the insertion point for a new element is O(n), and the subsequent insertion of the new element in the correct location is O(1). But you're probably better off just using a straightforward Python list.
