Mastering Basic Text File Handling and Data Filtering

Many real-world applications begin with processing data stored in simple text files, making file handling an indispensable skill for any programmer. This course guides you through the foundational concepts of reading, parsing, and filtering sequential text data. By the end, you will be able to efficiently extract specific information from large datasets using robust programming patterns. What you'll learn: * Understand the principles of sequential file reading, including specifying file paths and access modes. * Apply safe file handling practices using context managers to ensure resources are properly closed. * Master core string methods for searching, splitting, and manipulating individual lines of text content. * Practice using iterative structures and conditional logic to filter data based on prefixes, suffixes, or substrings. * Configure simple data processing pipelines that read source files and output filtered results. The content starts with defining file paths and modes, progresses through line-by-line processing techniques, and culminates in practical exercises focused on filtering records based on common criteria. This course is designed for absolute beginners in programming. No prior experience with file systems or data processing is required.
