![]() 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. 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.
