| About PyYAML |
| ============ |
| |
| YAML is a data serialization format designed for human readability 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. |
| |
| |
| Example |
| ======= |
| |
| >>> import yaml |
| |
| >>> yaml.full_load(""" |
| ... name: PyYAML |
| ... description: YAML parser and emitter for Python |
| ... homepage: https://github.com/yaml/pyyaml |
| ... keywords: [YAML, serialization, configuration, persistence, pickle] |
| ... """) |
