About this course

Understanding how data is organized is the key to writing efficient and scalable code. This text-based course guides you through the logic and implementation of linked lists, moving beyond Python's built-in types to help you build your own custom data structures from scratch. You will transition from a basic understanding of objects to creating complex, interconnected data systems. By the end of this course, you will be able to design, implement, and manipulate various linked list types while understanding their performance implications in real-world software. What you'll learn: - Understand the fundamental differences between Python's built-in lists and custom linked structures - Build singly, doubly, and circular linked lists using modern Python classes and objects - Master core operations including node insertion, deletion, and traversal for various scenarios - Apply modern Python type hints to ensure data structure integrity and code clarity - Analyze the time and space complexity of linked list operations using Big O notation - Practice logical problem-solving through written implementation challenges and brain teasers The course begins with essential terminology and the conceptual foundations of nodes before moving into step-by-step implementation through written explanations and code examples. You will explore different architectural patterns and conclude with exercises designed to sharpen your algorithmic thinking. This course is designed for learners who are comfortable with Python basics like variables and classes and want to dive deeper into computer science fundamentals. No prior experience with data structures is required. Start building more efficient Python applications by mastering custom data structures today.

Overall a good learning experience. The structure made sense, and the examples were relevant, though I felt some topics could have been explored more thoroughly.

It's a good course if you have some prior knowledge. For absolute beginners, some concepts might be a bit challenging. The structure is logical, though.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.

Good introduction to the topic. The structure was logical, and most of the examples were relevant, though I wished for more depth in certain areas.

It's a solid course. The structure is logical and most of the examples were helpful. Could use a few more real-world scenarios though.

It's a decent introduction. Could benefit from more diverse examples and a slightly better flow between modules.
