WebFeb 26, 2024 · Do time complexities differ between list and deque for Bisect/Insort? As far as I know, list in Python is implemented using array, while deque is implemented using double linked list. In either case, the binary search of a certain value takes O (logn) time, but if we insert to that position, array takes O (n) while double linked list takes O (1).

Python Bisect Algorithm: Bisect And Insort Functions

WebThe function insort_right () inserts a new element into an already sorted list. If the list has one or more entries as the new entry it is inserted next to the right most position of such existing entries. Calling insort_right () is equivalent to invoking the function bisect_right () followed by the list.insert () method.

WebJun 23, 2010 · Dicts are unordered, so using bisect on them is meaningless. I can think of a couple of options: 1) Keep the data in a sorted list of (key, value) tuples.
