🌟 "Mastering Regular Expressions in Python: Simplify Text Parsing and Matching" 🌟

🔍 Welcome to **Chapter 10** of the FreeCodeCamp Legacy Python series, where we dive deep into the powerful world of **regular expressions** (RegEx). In this chapter, we’ll explore how to use RegEx to match, search, and extract patterns from text. Regular expressions may seem cryptic at first, but they are a versatile tool that can help you efficiently parse and manipulate text in your Python programs.

📌 Key Highlights in Regular Expressions:

- Learn the basics of **regular expressions (RegEx)**, including their use for matching patterns in strings and extracting data.
- Understand how RegEx provides a **concise and flexible way** to search for text patterns such as particular characters, words, or patterns of characters.
- Explore the **powerful search and find operations** using Python’s built-in `re` library.
- Discover how **special characters** like `^`, `$`, `.`, `\s`, `\S`, and more, allow you to create **custom search patterns** to fine-tune your matching process.

📊 Elevate Your Python Text Parsing Skills:

This chapter introduces you to a tool that allows you to search and extract specific text patterns in complex data. By the end of this lesson, you'll gain confidence using regular expressions to automate text matching tasks, whether it’s finding emails, phone numbers, or any repetitive pattern in large blocks of text.

✏️ Practical RegEx Techniques:

We’ll break down practical examples of how to:
- Match lines that start or end with specific text using `^` and `$`.
- **Fine-tune your matching** with non-whitespace characters and multiple occurrences using special RegEx syntax.
