Aug 16, 2024 · In this article, we will discuss the Data Structures in the Python Programming Language and how they are related to some specific Python Data Types. We will discuss all the in-built data structures like list tuples, dictionaries, etc. as well as some advanced data structures like trees, graphs, etc.

1 day ago · Data Structures¶ This chapter describes some things you’ve learned about already in more detail, and adds some new things as well. 5.1. More on Lists¶ The list data type has some more methods. Here are all of the methods of list objects: list. append (x) Add an item to the end of the list. Equivalent to a[len(a):] = [x]. list. extend (iterable)
In this tutorial, you'll learn about Python's data structures. You'll look at several implementations of abstract data types and learn which implementations are best for your specific use cases.

A linked listis a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers as shown in the below image: Program: Output:
A stackis a linear structure that allows data to be inserted and removed from the same end thus follows a last in first out(LIFO) system. Insertion and deletion is known as push() and pop() respectively. Program: Output:
A queueis a linear structure that allows insertion of elements from one end and deletion from the other. Thus it follows, First In First Out(FIFO) methodology. The end which allows deletion is known as the front of the queue and the other end is known as the rear end of the queue. Program: Output:
A treeis a non-linear but hierarchical data structure. The topmost element is known as the root of the tree since the tree is believed to start from the root. The elements at the end of the tree are known as its leaves. Trees are appropriate for storing data that aren’t linearly connected to each other but form a hierarchy. Program: Output:
A Graphis a non-linear data structure consisting of nodes and edges. The nodes are sometimes also referred to as vertices and the edges are lines or arcs that connect any two nodes in the graph. A Graph consists of a finite set of vertices(or nodes) and set of Edges which connect a pair of nodes. Program: Output:
Hash maps are indexed data structures. A hash map makes use of a hash functionto compute an index with a key into an array of buckets or slots. Its value is mapped to the bucket with the corresponding index. The key is unique and immutable. In Python, dictionaries are examples of hash maps. Program: Output:
Jun 6, 2024 · At its core, a data structure is a method of organizing data that facilitates specific types of queries and operations on that data. We'll begin by covering linear data structures like arrays, lists, queues, and stacks.
