43 About PyYAML
44 ============
46 YAML is a data serialization format designed for human readability and
47 interaction with scripting languages.  PyYAML is a YAML parser and
48 emitter for Python.
50 PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
51 support, capable extension API, and sensible error messages.  PyYAML
52 supports standard YAML tags and provides Python-specific tags that allow
53 to represent an arbitrary Python object.
55 PyYAML is applicable for a broad range of tasks from complex
56 configuration files to object serialization and persistance.
59 Example
60 =======
62 >>> import yaml
63 >>> print yaml.load("""
64 ... &A {
65 ...     direct self reference: *A,
66 ...     indirect self references: [*A, *A, *A]
67 ... }
68 ... """)
69 {'direct self reference': {...},
70 'indirect self references': [{...}, {...}, {...}]}
