Python Bisect Module tutorial | fast insertion into sorted lists

Показать описание
This tutorial video explains how to use the Python Bisect module to do very fast insertion of new items into an already sorted List. The Bisect library can either return an insert index for you, or can insert the item for you. Four functions - bisect_left, bisect_right, insort_left, and insort_right functions - are all explained with examples. And two example implementations show how to get_grades or find an item.

Thank you for this video! I wasn't aware of the bisect module yet, but it's certainly gonna be helpful in many situations.

Hi Joe,
Thanks for the video, I had a question on this. You had mentioned O(log n) speed for insertion - looking at the documentation, it mentions:
"Keep in mind that the O(log n) search is dominated by the slow O(n) insertion step."
So it sounds like inserting would still be O(n) speed, even though finding the item is O(log n)

Joe James: A very typical requirement is to have a dynamic, ordered collectio of elements such as a binary search tree. Is there a python version that provides a BST out of the box in the standard library? c++ has it, java has it, but python doesn't appear to have one. what a pity!
