2.9.1.1. pycsamt.seg.base#

Base classes for SEG-EDI objects and components.

This module provides a small reusable base class that standardizes: string representation, pretty printing of key/value lines in the SEG-EDI style, and simple (de)serialization helpers.

Subclasses only need to: - set _section (e.g., "HEAD", "INFO", …) - define typed attributes (via __annotations__ or dataclass) - optionally override validate or value formatting if needed.
