sort a Python dictionary by value 首先要明确一点,Python的dict本身是不能被sort的,更明确地表达应该是“将一个dict通过操作转化为value有序的列表” 有以下几种方法: 1. importoperator x= {1: 2, 3: 4, 4: 3, 2: 1, 0: 0} sorted_x= sorted(x.items(), key=operator.itemgetter(1))#sorted...
Python中Dictionary的sort by key和sort by value(排序)Leave a reply Python中的Dictionary类似于C++ STL中的Map Sort by value #remember to import from operator import itemgetter dict={...} #sort by value sorted(dict.items(), key=itemgetter(1), reverse=True) Sory by Key #sort by key sorted...
