Binary package “python3-yaml” in ubuntu bionic

YAML parser and emitter for Python3

 Python3-yaml is a complete YAML 1.1 parser and emitter for Python3. It can
 parse all examples from the specification. The parsing algorithm is simple
 enough to be a reference for YAML parser implementors. A simple extension API
 is also provided. The package is built using libyaml for improved speed.
