Sometimes, we want to parse a YAML file in Python.
In this article, we’ll look at how to parse a YAML file in Python.
How to parse a YAML file in Python?
To parse a YAML file in Python, we can use the PyYAML package.
To install it, we run:
pip install pyyaml
Then we write:
import yaml
with open("example.yaml", "r") as stream:
try:
print(yaml.safe_load(stream))
except yaml.YAMLError as exc:
print(exc)
to parse example.yaml, which has:
a list:
- 1
- 42
- 3.141
- 1337
- help
- €
a string: bla
another dict:
foo: bar
key: value
the answer: 42
We open the YAML file with open with read permission.
Then we call yaml.safe_load to load the open file stream.
From print, we get:
{'a list': [1, 42, 3.141, 1337, 'help', '€'], 'a string': 'bla', 'another dict': {'foo': 'bar', 'key': 'value', 'the answer': 42}}
A yaml.YAMLError will be raised if the file can’t be parsed.
Conclusion
To parse a YAML file in Python, we can use the PyYAML package.
