Python Regex: Finding Words with Prefixes and Substrings

Working with text data is a core task in modern software development, yet finding specific word patterns can quickly become complex using standard string methods alone. This course teaches you how to leverage the power of regular expressions (regex) in Python to identify, match, and extract words starting with specific prefixes or containing target substrings. You will transition from basic string searches to writing robust, flexible pattern-matching logic that handles real-world text processing challenges. What you will learn: Learn foundational regex syntax and Python's built-in re module; Master pattern matching for prefixes, suffixes, and complex word boundaries; Apply clean coding practices using Python's modern type hints for text-processing functions; Create robust validation patterns to filter and clean unstructured raw text; Practice debugging regular expressions using standard testing patterns. The course starts with essential text-matching terminology and foundational regex concepts before moving into practical, step-by-step pattern construction and text-filtering exercises. This course is designed for beginner Python developers and data enthusiasts who want to build a solid foundation in text processing without any prior regex experience.
