Name : PyYAML
Product : Fedora 29
Version : 5.1
Release : 1.fc29
URL : https://github.com/yaml/pyyaml
Summary : YAML parser and emitter for Python
Description :
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.
