Serializing YAML with PyYAML

Internal

• YAML in Python

Overview

The process of serialization to YAML is rendering an in-memory data structure as a YAML-formatted string. The simplest sequence of statements that does that is:

import yaml

data = {
    'color': 'red',
    'size': 10,
    'parts': ['top', 'middle', 'bottom']
}

yaml_string = yaml.dump(data)

The YAML-formatted string will be:

color: red
parts:
- top
- middle
- bottom
size: 10
