Build Grammar Rules with PyParsing Without Regex Maintenance

Problem

Regular expressions can be powerful but often become verbose and hard to maintain, especially when accounting for variable whitespace or special characters.

Solution

PyParsing offers a cleaner alternative. It lets you define grammar rules using Python classes, making the parsing logic explicit and easier to maintain.

PyParsing advantages over regex:

• Whitespace: Automatically handled without extra tokens
• Readability: Self-documenting code structure
• Data access: Use dot notation rather than numeric groups
• Scalability: Combine reusable components to build complex grammars
