        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

你可以使用PyYAML

pip install PyYAML

并在ipython控制台中：

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'}}
