PyYAML is a YAML parser and emitter for the Python programming language. 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.
