[YAML](http://www.yaml.org), YAML ain't markup language. Printer attributes: null="string": Display string instead of `null` for null/None values. no-undefined: Does not display resource data items with null values. version=VERSION: Prints using the specified YAML version, default 1.2. For example: printer = YamlPrinter(log.out) printer.AddRecord({'a': ['hello', 'world'], 'b': {'x': 'bye'}}) produces: --- a: - hello - world b: - x: bye Attributes: _yaml: Reference to the `yaml` module.
