Converting a YAML file to Python JSON object

Question

How can I load a YAML file and convert it to a Python JSON object?

My YAML file looks like this:

Section:     heading: Heading 1     font:          name: Times New Roman         size: 22         color_theme: ACCENT_2  SubSection:     heading: Heading 3     font:         name: Times New Roman         size: 15         color_theme: ACCENT_2 Paragraph:     font:         name: Times New Roman         size: 11         color_theme: ACCENT_2 Table:     style: MediumGrid3-Accent2 

Answer 1

you can use PyYAML

pip install PyYAML 

And in the ipython console:

In [1]: import yaml  In [2]: document = """Section:    ...:     heading: Heading 1    ...:     font:     ...:         name: Times New Roman    ...:         size: 22    ...:         color_theme: ACCENT_2    ...:     ...: SubSection:    ...:     heading: Heading 3    ...:     font:    ...:         name: Times New Roman    ...:         size: 15    ...:         color_theme: ACCENT_2    ...: Paragraph:    ...:     font:    ...:         name: Times New Roman    ...:         size: 11    ...:         color_theme: ACCENT_2    ...: Table:    ...:     style: MediumGrid3-Accent2"""    ...:       In [3]: yaml.load(document) Out[3]:  {'Paragraph': {'font': {'color_theme': 'ACCENT_2',    'name': 'Times New Roman',    'size': 11}},  'Section': {'font': {'color_theme': 'ACCENT_2',    'name': 'Times New Roman',    'size': 22},   'heading': 'Heading 1'},  'SubSection': {'font': {'color_theme': 'ACCENT_2',    'name': 'Times New Roman',    'size': 15},   'heading': 'Heading 3'},  'Table': {'style': 'MediumGrid3-Accent2'}} 

Answer 2

The PyYAML library is intended for this purpose

pip install pyyaml 

import yaml import json with open("example.yaml", 'r') as yaml_in, open("example.json", "w") as json_out:     yaml_object = yaml.safe_load(yaml_in) # yaml_object will be a list or a dict     json.dump(yaml_object, json_out) 

Notes: PyYAML only supports the pre-2009, YAML 1.1 specification.
ruamel.yaml is an option if YAML 1.2 is required.

pip install ruamel.yaml
