In this article, I have explained how to sort a list of dictionaries by value in ascending/descending order using Pyhton sorted(), sort(), lambda function, and itemgetter() functions with examples. Dictionary elements should be enclosed with ] Each element in the dictionary is in the form of key:value pairs. Sort dictionary by value in Python python - How do I sort a list of dictionaries by a value of Python List sort() Method - W3Schools What are Ordered. # Example 8: Sort a list of dictionaries having the same value for multiple keysĪ Python dictionary is a collection that is unordered, mutable, and does not allow duplicates. In the following sections, we'll explore different ways to sort a Python dictionary that include: sorting a dictionary by keys sorting a dictionary by values Sorting a dictionary by Keys The first way we can sort a dictionary is by its keys. Print(sorted(dict_list, key=emgetter('calories'))) # Example 7: Sort list of dictionaries without key existence Print(sorted(dict_list, key=emgetter('fruit_name'))) 4 Answers Sorted by: 69 Here is one way to do this: > sorted (ems (), keylambda e: e 1 2) ('item2', 8, 2, 3), ('item1', 7, 1, 9), ('item3', 9, 3, 11) The key argument of the sorted function lets you derive a sorting key for each element of the list. list is made of items (like in a dictionary), the list will be sorted by key then by value. # Example 6: Set emgetter() as key and sort Let us remind the usage of the inline sorting method sort(): >. Print(sorted(dict_list, key=lambda x: x.get('calories', 95))) # Example 5: Sort list of dictionaries using sorted() & get() Print(sorted(dict_list, key=lambda x: x.get('calories'))) By passing this list to the sorted () function, we can sort the tuples based on their first element (the keys). The items () method returns a list of key-value pairs as tuples. Example 1: Sort the dictionary based on values Here, keylambda item: item1 returns the values of each key:value pair. # Example 4: Sort list of dictionaries using sorted() & get() The simplest way to sort a dictionary by its keys is by using the sorted () function along with the items () method of the dictionary. By specifying a function to be applied to each element of the list, it is sorted according to the result of that function. # Example 3: Sort list of dictionaries when key doesn't exist To sort a list of dictionaries according to the value of the specific key, specify the key parameter of the sort() method or the sorted() function. This function takes in the list of dictionaries. What you now deal with is a key-value pair, which is sometimes a more appropriate data structure for many problems instead of a simple list. Print(sorted(dict_list, key=lambda x: x, reverse = True)) To sort a list of dictionaries by a value of the dictionary in Python, you can use the sorted() function. # Example 2: Sort list of dictionaries in descending order Print(sorted(dict_list, key=lambda x: x)) You may also want to check the following guide that explains how to extract dictionary keys as a list.# Example 1: Sort list of dictionaries using sorted() & lambda python - Sort dictionary with multiple values - Stack Overflow python - How do I sort a list of dictionaries by a value of python - How to count occurrences. To start with a simple example, let’s create the dictionary below: my_dict = Examples of Extracting Dictionary Values as a List in Python Example 1: Use a list() function to extract dictionary values as a list Next, you’ll see few examples of extracting dictionary values as a list. (2) Using a List Comprehension: my_list = (1) Using a list() function: my_list = list(my_dict.values()) We can sort the dictionary in python using keys with the help of the keys() method and for a loop. Below are 3 methods to sort the dictionary using keys. Here are 3 approaches to extract dictionary values as a list in Python: Apart from sorting the dictionary using values, we can also sort the dictionary using the keys component.
