- and interaction with scripting languages. PyYAML is a YAML parser
- and emitter for Python.
-
- PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
- support, capable extension API, and sensible error messages. PyYAML
- supports standard YAML tags and provides Python-specific tags that
- allow to represent an arbitrary Python object.
-
- PyYAML is applicable for a broad range of tasks from complex
- configuration files to object serialization and persistence.

-PyYAML - The next generation YAML parser and emitter for Python.
-
-To install, type 'python setup.py install'.
-
-By default, the setup.py script checks whether LibYAML is installed
-and if so, builds and installs LibYAML bindings. To skip the check
-and force installation of LibYAML bindings, use the option '--with-libyaml':
-'python setup.py --with-libyaml install'. To disable the check and
-skip building and installing LibYAML bindings, use '--without-libyaml':
-'python setup.py --without-libyaml install'.
-
-When LibYAML bindings are installed, you may use fast LibYAML-based
-parser and emitter as follows:
-
- >>> yaml.load(stream, Loader=yaml.CLoader)
- >>> yaml.dump(data, Dumper=yaml.CDumper)
-
-If you don't trust the input stream, you should use:
-
- >>> yaml.safe_load(stream)
-
-PyYAML includes a comprehensive test suite. To run the tests,
-type 'python setup.py test'.
-
-For more information, check the PyYAML homepage:
-'https://github.com/yaml/pyyaml'.
-
-For PyYAML tutorial and reference, see:
-'http://pyyaml.org/wiki/PyYAMLDocumentation'.
-
-Discuss PyYAML with the maintainers in IRC #pyyaml irc.freenode.net.
-
-You may also use the YAML-Core mailing list:
-'http://lists.sourceforge.net/lists/listinfo/yaml-core'.
-
-Submit bug reports and feature requests to the PyYAML bug tracker:
-'https://github.com/yaml/pyyaml/issues'.

-The PyYAML module was written by Kirill Simonov <xi@resolvent.net>.
-It is currently maintained by the YAML and Python communities.
