PyYAML features

  • a complete YAML 1.1 parser. In particular, PyYAML can parse all examples from the specification. The parsing algorithm is simple enough to be a reference for YAML parser implementors.
  • Unicode support including UTF-8/UTF-16 input/output and \u escape sequences.
  • low-level event-based parser and emitter API (like SAX).
  • high-level API for serializing and deserializing native Python objects (like DOM or pickle).
  • support for all types from the YAML types repository. A simple extension API is provided.
  • both pure-Python and fast LibYAML-based parsers and emitters.
  • relatively sensible error messages.
