I am writing yaml file like this
with open(fname, "w") as f: yaml.safe_dump({'allow':'', 'deny': ''}, f, default_flow_style=False, width=50, indent=4) This outputs:
allow: '' I want to output as
allow: How can I do that?

Empty values: null can be used to represent an empty value, such as an empty list or an empty string. Placeholder values: null can be used as a placeholder value when the actual value is not yet known.
Nulls in YAML can be expressed with null or ~ .
As you can see, since both l-document-prefix and l-any-document are optional, an empty YAML stream is valid – but contains no document. If you're asking whether l-any-document can produce the empty string, the answer is no.
For None type to be read from python use null in yaml
A YAML file test.yml like this
foo: null bar: null will be read by python as
import yaml test = yaml.load(open('./test.yml')) print(test) foo: None bar: None If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
