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...

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] ...
用sort() l.sort(lambda a,b :cmp(a[1],b[1]))(cmp前加“-”表示降序排序) dic={'a':1,'c':3,'b':22}#d[0]表示用key排序,d[1]表示用value排序printsorted(dic.items(), key=lambdad: d[0])printsorted(dic.items(), key=lambdad: d[1])#用内置函数排序只返回key值的列表#或反序...
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...
When we use thesorted()method to sort the list of dictionaries by value with a specified key, which does not exist in the dictionary. It will raise theKeyError. # Sort list of dictionaries when key doesn't exist print(sorted(dict_list, key=lambda x: x['calories'])) ...
Sort (descending) the said dictionary elements by value: {'Black': 5, 'Pink': 4, 'Green': 3, 'White': 2, 'Red': 1} Flowchart: For more Practice: Solve these Related Problems: Write a Python script to sort a dictionary by its values in ascending order using lambda functions. ...
