pip install pyyaml
import yaml result = yaml.load(yaml_string) # to python list or dict string = yaml.dump(py_object) # NOTE: unlike the json module, the method here is load/dump, not loads/dumps
YAML uses three dashes (“---”) to separate documents within a stream. Three dots ( “...”) indicate the end of a document without starting a new one, for use in communication channels.
empty string in yaml is '' or "", if you have a blank entry, it will be converted to None you don't need to quote strings in yaml
for dumping, when dumping to a file, do this
with open('file.yml', 'w') as f: yaml.dump(data, f, default_flow_style=False, allow_unicode=True)
