How can I parse a YAML file in Python

How can I parse a YAML file in Python?

Solution

The easiest method without relying on C headers is PyYaml (documentation), which can be installed via pip install pyyaml:

import yaml

with open("example.yaml") as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

yaml.load() also exists, but yaml.safe_load() should always be preferred to avoid introducing the possibility for arbitrary code execution. So unless you explicitly need the arbitrary object serialization/deserialization use safe_load.

The PyYaml project supports versions up through the YAML 1.1 specification. If YAML 1.2 specification support is needed, see ruamel.yaml as noted in this answer.

Also, you could also use a drop in replacement for pyyaml, that keeps your yaml file ordered the same way you had it, called oyaml. View snyk of oyaml here
