Python Modules and Libraries for Computer Science Students

Building a solid foundation in programming means learning how to organize code efficiently and reuse existing tools. This text-based course guides you through the core concepts of Python modules, packages, and standard libraries, helping you write cleaner and more structured code. You will transition from writing single-file scripts to developing modular, scalable programs. What you'll learn: Understand the foundational concepts of namespaces, import statements, and module scope; Use built-in Python modules such as math, random, and statistics for everyday computing; Create, organize, and import your own custom modules and packages; Apply modern Python conventions including type hints and basic virtual environments to keep your projects clean; Practice debugging import errors and managing dependency paths. We begin with essential terminology and the mechanics of how Python locates files, then progress to hands-on written exercises where you will build and structure your own multi-file projects. This course is designed specifically for beginners and computer science students looking to master modular programming without any complex prerequisites. Start reading today to write cleaner, more professional Python code.
