Master Data Structures with Hands-on Python

Master Data Structures with Hands‑on Python – taught by Youssef Ahmed Abdel Latif – is a free data structures Udemy course that lets you learn core computer‑science concepts while coding in Python. Updated July 2026, the training covers arrays, linked lists, stacks, queues, hash tables, trees and graphs, giving you practical skills that translate directly to technical interviews and real‑world projects. By completing the course you earn a Udemy certificate of completion, adding a verified credential to your résumé or LinkedIn profile.

What You'll Learn

• Build fully functional arrays, stacks and queues from scratch using native Python syntax.
• Master singly, doubly and circular linked‑list implementations and understand their runtime characteristics.
• Learn how hash tables, hash sets and Python dictionaries store and retrieve data in constant time.
• Understand tree traversal algorithms (pre‑order, in‑order, post‑order) and apply them to solve hierarchical problems.
• Create graph representations and explore depth‑first and breadth‑first search techniques for network analysis.
• Implement real‑world mini‑projects that combine multiple data structures to solve algorithmic challenges.
• Analyze the trade‑offs of each data structure to choose the optimal solution for a given problem.
• Apply data‑structure knowledge to boost performance in coding interviews and AI‑oriented applications.

What This Course Covers

Linear Data Structures

• Arrays: memory layout, indexing, and basic operations in Python
• Lists and deques: dynamic resizing, insertion, deletion, and slicing techniques
• Stacks: LIFO implementation, use cases such as expression evaluation
• Queues: FIFO behavior, circular queue design, and real‑time processing examples

Linked Lists

• Singly linked list: node creation, traversal, insertion, and deletion
• Doubly linked list: bidirectional navigation and efficient deletions
• Circular linked list: looped structures for round‑robin scheduling
• Practical exercises: building a playlist manager using linked lists

Hash‑Based Structures

• Hash functions: design principles and collision handling strategies
• Hash tables and hash maps: key‑value storage, look‑up complexity, and Python dictionaries
• Hash sets: uniqueness enforcement and fast membership tests
• Real‑world scenario: implementing a caching layer for API responses

Trees and Graphs

• Binary trees: construction, traversal, and height‑balanced variants
• Search trees (BST, AVL): insertion, deletion, and search complexities
• Graph representations: adjacency lists vs. adjacency matrices in Python
• Algorithms: depth‑first search (DFS), breadth‑first search (BFS), and shortest‑path basics

Hands‑On Projects

• Project 1: Build a simple text editor using stacks for undo/redo functionality
• Project 2: Create a URL shortener employing hash maps for fast look‑ups
• Project 3: Develop a maze solver using graph traversal techniques
• Project 4: Design a recommendation engine prototype leveraging tree structures
