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 ...
Assume we have a dictionary like below, exampleDict={"first":3,"second":4,"third":2,"fourth":1} Python Sort Dictionary by Value - Only Get the Sorted Values Useoperator.itemgetterto Sort the Python Dictionary importoperator sortedDict=sorted(exampleDict.items(),key=operator.itemgetter(1))#...
Sort a dictionary by values¶To sort the dictionary by values, you can use the built-in sorted() function that is applied to dict.items(). Then you need to convert it back either with dictionary comprehension or simply with the dict() function:...
# Define a function 'sort_dict_by_value' that takes a dictionary 'd' and an optional 'reverse' flag.# It returns the dictionary sorted by values in ascending or descending order, based on the 'reverse' flag.defsort_dict_by_value(d,reverse=False):returndict(sorted(d.items(),key=lambda...
items.sort() return [value for key, value initems] #又一个按照key值排序,貌似比上一个速度要快点 defsortedDictValues2(adict): keys =adict.keys() keys.sort() return [dict[key] for key inkeys] #还是按key值排序,据说更快。。。而且当key为tuple的时候照样适用 ...
It will return a sorted dictionary.Example# Importing operator module import operator # Create a dictionary data = {"a": 1, "c": 3, "b": 5, "d": 4} # Print original dictionary print("Original dictionary:") print(data) # Sort dictionary by value result = sorted(data.items(), key...

In Python, the dictionary class doesn't have any provision to sort items in its object. Hence, some other data structure, such as the list has to be used to be able to perform sorting.
dictionary.sort(key=lambda x: x[1], reverse=True) 其中,key参数指定一个函数,用于从字典条目中提取比较值。reverse参数设置为True表示按降序排列,即从大到小排列。例如,上述代码演示了如何使用sort方法对字典按照值的大小进行降序排列: fruits = ['apple': 3, 'banana': 2, 'orange': 5] ...
By: Rajesh P.S.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...
