One way is to write zero or more key-value pairs between curly braces. There are different ways of creating a dictionary in Python. If you’re new to Python and don’t know much about data structures, I suggest taking our course Python Data Structures in Practice, which contains over 100 interactive exercises to help you get a comprehensive understanding of Python’s data structures. In this article, we’ll learn how to sort a dictionary in Python in great detail. But we can sort a dictionary in Python, either sorting by key or by value. key-value pairs) in a dictionary are not sorted by default, nor do they have an index.

The keys, as the name suggests, are used for accessing the values. A dictionary can be defined as an unordered collection of key-value pairs. To create robust and performant software products, one must know how to efficiently use data structures.Īlong with lists, tuples, and sets, dictionaries are one of Python’s most used built-in data structures. ![]() Do you want to learn how to sort a dictionary in Python?
