StrictYAML

StrictYAML is a type-safe YAML parser and validator for Python, focusing on a restricted, unambiguous subset of the YAML specification. It prioritizes a clear API, strict validation, human-readable exceptions, and the ability to round-trip (read, modify, and write) YAML while preserving comments. The current version is 1.7.3, with an active but irregular release cadence of patches and minor versions.
