Code to sort Python dictionary using the items() method Here is an example to sort dictionaries based on keys. The above output is a representation of the dictionary that gives us a way to iterate through the dictionary without list generation. The following example shows how a dictionary of fruits can be used with the items method to generate dict_items that has pairs of keys and values. Let's take an example to understand the working of this method. Here is an example to sort dictionary keys using the items() method. We can also use the items() method to get the dictionary items and sort the dictionary over the keys. Code to sort Python dictionary using dictionary comprehension Here's an example to sort a dictionary by its keys.

#Python sort list of dictionaries on key how to

If you want to sort the dictionary completely by using its keys, we'll look at how to do that in the code below. It's important to note that the sorted function returns a new list of the sorted keys, rather than modifying the dictionary in place. Code to sort keys of Python dictionary using keys() method The code below shows how to use the keys() method to sort list of keys in a dictionary. We can also use the keys() method to get the keys of a dictionary. The following code explains how to use the reverse parameter of the sorted function to reverse sort the keys of the fruits dictionary. Code to reverse sort keys of Python dictionary If we want to sort the keys in reverse order, we can pass in the reverse parameter as True. The following example explains how to use the sorted function to get the keys of a dictionary sorted inside the sorted_dict_keys list. When the entire dictionary is given to the sorted function, only the keys are sorted and returned in a new list. Here is an example of sorting dictionary keys in ascending and descending order. By default, the sorted function will sort the keys in ascending order.

The sorted function can sort the keys in ascending or descending order and string in alphabetical order and returns a new list having those keys. To sort a dictionary by its keys, we can simply use the sorted function and pass in the dictionary as the iterable. This is useful if you want to present the data in a certain order, such as alphabetically. The first way we can sort a dictionary is by its keys. In the following sections, we'll explore different ways to sort a Python dictionary that include: Sorting data in a dictionary allows us to access data faster and reduce data complexity. However, one thing that dictionaries do not natively support is sorting. How to sort a dictionary in Python?ĭictionaries are a powerful data structure in Python, providing a convenient way to store and access data using key-value pairs. It also provides a more robust interface for creating dictionaries, as opposed to just the literal notation of curly braces. This makes it easier for developers to build complex data structures, such as nested dictionaries or multi-level hierarchical dictionaries. The dict() constructor allows developers to create a dictionary from any iterable object, including lists and tuples. The following example explains how to use the dict constructor with list_data to get the data stored inside the my_dict dictionary. The following example explains how to use the dict constructor with tuple_data to get the data stored inside the my_dict dictionary.Ĭreate Python dictionary using a list of key-value pairs Create Python dictionary using a tuple of key-value pairs Before Python 3.6, we used to rely on OrderedDict class of the collections module to keep track of the insertion order in Python dictionaries. This constructor keeps track of the insertion order of key-value pairs in the dictionary. Python dictionaries can also be created using the dict() constructor by simply providing a list or tuple of comma-separated key-value pairs. On the other hand, Claudia, femaleand 24are their respective values. In this example, name, gender, and ageare the keys. For beginners, here is an example that shows the simplest syntax to create a Python dictionary: There are multiple ways to create dictionaries in Python.

#Python sort list of dictionaries on key install

It is highly recommended that you install the latest version of Python 3 to write and run our Python programs. Throughout this blog / Python tutorial, we will use Python 3 and you can install any version of Python 3. It's no wonder that Python dictionaries have become such a popular tool for developers! How to create a Python dictionary? They allow you to quickly lookup values based on a key, store multiple values for the same key, and even add new items to the dictionary without having to re-create it from scratch. Python dictionaries are an incredibly powerful and versatile data structure.
