Building a Wordcount Tool in Python for Multiple Files

Processing text data across multiple documents is a fundamental task in data engineering and software development. This text-based course helps you build a command-line utility that reads multiple files, counts their contents, and outputs structured summaries. You will start with the core concepts of file streams and error handling, then move on to writing clean, maintainable code. What you'll learn: Understand core file-handling mechanics and stream operations in Python; Manage multiple file inputs safely using modern path-handling libraries; Implement robust exception handling for missing or unreadable files; Calculate precise counts for lines, words, and bytes across diverse text encodings; Generate clean, formatted console summaries of aggregated file data; Apply modern Python type hints to ensure your utility is robust and maintainable. This course begins with essential file-reading terminology and foundational concepts before guiding you through structured coding exercises. It is designed for beginners who have a basic grasp of Python syntax and want to build practical command-line tools. Start learning today and master the fundamentals of file processing.
