A simple filtering syntax tree in Python

Read Original

This technical article explains how to implement a basic syntax tree in Python to serve as the foundation for a Domain-Specific Language (DSL) focused on data filtering. It discusses the trade-offs of creating a DSL, outlines a tree structure using Python dictionaries to represent logical and predicate operators, and provides a recursive evaluation method for filtering conditions like 'greater than' or 'and/or'.
