Introduction to Arrays and Lists in Computer Science

Storing and organizing data efficiently is one of the most fundamental skills in computer science. If you are new to programming, understanding how arrays and lists work is the essential first step toward writing clean, functional code. This text-based course guides you from absolute beginner concepts to a confident understanding of how collections of data are structured, stored, and manipulated in modern programming. You will build a solid mental model of computer memory and data organization. What you'll learn: - Understand the core concepts of arrays, indexing, and sequential data storage. - Learn how computer memory allocates space for different types of data collections. - Apply fundamental operations such as searching, sorting, and updating elements. - Practice writing clean code using modern list comprehensions and type hints. - Manipulate multi-dimensional arrays to represent complex data structures. - Solve practical logic problems using basic array algorithms. The course begins with foundational definitions and memory layouts before moving step-by-step into iteration techniques, multi-dimensional structures, and common algorithmic patterns. It is designed specifically for beginners, students, and educators looking for a clear, structured introduction to data collections with no prior programming experience required.
