To sort a dictionary by its values in Python, you can use the sorted() function along with a lambda function as the key argument. The lambda function is used to extract the values from the dictionary, and sorted() returns a new list of tuples containing the key-value pairs sorted based...

注;一般来说,cmp和key可以使用lambda表达式。 字典排序实现: 参见cookbook,Recipe 5.1. Sorting a Dictionary讲述了字典排序的方法; 前面已说明dictionary本身没有顺序概念,但是总是在某些时候,但是我们常常需要对字典进行排序,怎么做呢?下面告诉你: 方法1:最简单的方法,排列元素(key/value对),然后挑出值。字典的items...
按照value进行排序 print sorted(dict1.items(), key=lambda d: d[1]) 下面给出python内置sorted函数的帮助文档: sorted(...) sorted(iterable, cmp=None, key=None, reverse=False) --> new sorted list 看了上面这么多种对dictionary排序的方法,其实它们的核心思想都一样,即把dictionary中的元素分离出来放...
按照value排序可以用 sorted(d.items, key=lambda d:d[1]) 若版本低不支持sorted 将key,value 以tuple一起放在一个list中 l = [] l.append((akey,avalue))... 用sort() l.sort(lambda a,b :cmp(a[1],b[1]))(cmp前加“-”表示降序排序)...
