Chapter 5: Custom Data Structures: Building From Scratch

In this chapter, we delve into the world of custom data structures, as we explore the design and implementation of various data structures in Python. Building from scratch, we will uncover the inner workings of these structures, enabling you to understand and utilize them effectively in your programming tasks.

First, we start by examining the design and creation of a simple stack using lists. Understanding how stacks work and their applications is crucial for any developer, and by implementing our own stack, we gain a deeper understanding of this fundamental data structure.

Next, we explore the creation of a queue using Python’s deque. Queues are another essential data structure, and by utilizing the deque functionality, we can build a highly efficient and versatile queue implementation.

Moving forward, we discuss the implementation of trees and graphs in Python. Trees are hierarchical structures widely used in various domains, and graphs represent relationships between objects. We will cover the essential concepts and techniques to build and manipulate these data structures in Python.

Finally, we delve into techniques for balancing and searching in trees. Balancing trees is crucial for optimizing their performance, and by examining popular balancing techniques, we can ensure our trees operate efficiently. Additionally, exploring search algorithms allows us to efficiently locate and retrieve data from our data structures.

By the end of this chapter, you will have gained invaluable knowledge on designing and implementing custom data structures in Python. This understanding is essential for any developer looking to elevate their skills to the next level and harness the full power of Python’s data manipulation capabilities.
