ruamel.yaml.bytes

This plug-in adds a method dump_to_bytes to the ruamel.yaml.YAML instance that returns a (UTF-8) bytes array

Installation

The module can be installed from PyPI using:

pip install ruamel.yaml.bytes

This module is dependent on ruamel.yaml, so you do not have to explicitly make your module depending on both.

Usage

import ruamel.yaml

yaml = ruamel.yaml.YAML(typ=['rt', 'bytes'])
data  = dict(abc=42, help=['on', 'its', 'way'])
print('retval', yaml.dump_to_bytes(data).decode('utf-8'))
print('>>>> done')

which gives:

retval abc: 42
help:
- on
- its
- way
>>>> done

Please note that there is no final newline added to the bytes array returned, and that the >>>> done is on the next line is caused by the print() function adding a newline by default. Alternatively the first call to print could be:

print('retval', yaml.dump_to_bytes(data, add_final_eol=True).decode('utf-8'), end='')

with the same effect.

.dump_to_bytes() can be shortened to .dumpb()
