Python Word Counter: Processing Multiple Files

When writing text processing tools, handling a single file is only the beginning. To build truly useful scripts, you must know how to safely read, analyze, and aggregate data from multiple files simultaneously. This text-based course guides you through expanding a Python word count program into a robust command-line utility. You will learn to handle file system operations, process text streams, and generate clean summary statistics just like professional terminal tools. What you'll learn: Understand core file handling concepts and how Python manages system I/O; Read and process multiple text files sequentially using robust error handling; Calculate precise line, word, and byte counts for individual files; Aggregate data to generate a clean, consolidated summary table; Apply modern Python type hinting to ensure your code is maintainable and self-documenting; Use path-handling libraries to safely navigate directories and file paths. You will start with fundamental file I/O concepts and basic text parsing before moving step-by-step toward building a complete multi-file terminal utility. This course is designed for beginner Python programmers who want to transition from basic syntax to writing practical, real-world automation scripts. No advanced system administration experience is required. Start reading to build your own robust file-processing tools today.
