Fedora 34: FEDORA-2021-a2c9d0fd67 High: OpenSSL Vulnerability

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.
