Python Text File Handling for High School Computer Science

Working with external files is a fundamental skill in programming and a core requirement for high school computer science curricula. This course provides a clear, structured path to understanding how Python interacts with text files, helping you move from basic syntax to confident data manipulation. You will learn how to open, read, modify, and close files securely while avoiding common programming pitfalls. By completing this text-based course, you will be able to write clean, efficient Python scripts that process textual data and solve practical file-handling problems with ease. What you'll learn: - Understand foundational file-handling concepts, including file paths and access modes - Read data from text files using methods like read, readline, and readlines - Write and append new information to text files without overwriting existing data - Apply pythonic resource management using the context manager with-statement - Practice data parsing techniques to filter, search, and manipulate text file contents - Implement basic error handling to manage missing files and input-output exceptions This course begins with essential definitions and core concepts of file storage before moving into step-by-step code demonstrations and practical exercises. You will progress from opening your very first text file to writing robust scripts that process complex text patterns. This course is designed for beginners, high school computer science students preparing for exams, and self-taught programmers looking to solidify their Python fundamentals. No prior file-handling experience is required, though a basic understanding of Python variables and loops is recommended.
