到底有多少种方法可以实现对dictionary的内容进行排序输出呢?下面摘取了 一些精彩的解决办法。 #最简单的方法,这个是按照key值排序: def sortedDictValues1(adict): items = adict.items() items.sort() return [value for key, value in items] #又一个按照key值排序,貌似比上一个速度要快点 def sortedDict...
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:...
Here, we will use thesorted()method by passing the list comprehension. Where list comprehension is a shorter syntax to create a new list based on the values of an existing list. Example # Importing operator moduleimportoperator# Create a dictionarydata={"a":1,"c":3,"b":5,"d":4}# ...
[ v for v insorted(di.values())] #用lambda表达式来排序,更灵活: sorted(d.items(), lambda x, y:cmp(x[1], y[1])), 或反序: sorted(d.items(), lambda x, y: cmp(x[1], y[1]), reverse=True) #用sorted函数的key参数(func)排序: # 按照value进行排序 print sorted(dict1.items()...
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))# Out: [('fourth', 1), ('third', 2), ('first', 3), ('second', 4)] ...
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...
(x).most_common()[::-1] [(0, 0), (2, 1), (1, 2), (4, 3), (3, 4)] >>> #To get a dictionary sorted by values >>> from collections import OrderedDict >>> OrderedDict(Counter(x).most_common()[::-1]) OrderedDict([(0, 0), (2, 1), (1, 2), (4, 3), (3, ...
def sortedDictValues1(adict): items = adict.items() items.sort() return [value for key, value in 1. 2. 3. 4. 5. 6. 方法2:使用排列键(key)的方式,挑出值,速度比方法1快。字典对象的keys()方法返回字典中所有键值组成的列表,次序是随机的。需要排序时只要对返回的键值列表使用sort()方法。
Sorting by values requires specifying a sort key using a lambda function or itemgetter().By the end of this tutorial, you’ll understand that:You can sort a dictionary by its keys using sorted() with .items() and dict(). To sort by values, you use sorted() with a key function like...
Then, theforloop is utilized to find keys for each of the values present by iterating over the sorted values. Thekey:valuepairs that are found are then represented in the sorted order through a fresh dictionary. We should note that by using thesorted()function on the dictionary, we cannot...
