python3.x - python bisect模块中的insort是什么意思？

问题描述

问 题

import bisect
scores = [(100, 'perl'), (200, 'tcl'), (400, 'lua'), (500, 'python')]
bisect.insort(scores, (300, 'ruby'))

如上所示，insort这个单词似乎不存在，那这是什么意思呢？是 in sort吗？

解决方案

官方文档：

This module provides support for maintaining a list in sorted order without having to sort the list after each insertion. For long lists of items with expensive comparison operations, this can be an improvement over the more common approach. The module is called bisect because it uses a basic bisection algorithm to do its work. The source code may be most useful as a working example of the algorithm (the boundary conditions are already right!)

用于向一个有序的列表 插入数据， 插入后自动有序
