Łukasz Langa added the comment:
Michael, what you wish is already a part of configparser. Let's use this as an
example:
>>> p = configparser.ConfigParser()
>>> p.read_string("""
... [one]
... opt=val
... [two]
... num=1
... str=bzz
... bool=true
... """)
When asking for a specific section, you get a SectionProxy object. It has a
dict-like API but is not a dict:
>>> p['two']
<Section: two>
>>> isinstance(p['two'], dict)
False
The reason for that is two-fold: firstly this enables us to make changes made
on a section object persistent within the main parser. Secondly, this enables
us to add configparsser-specific functionality (like dynamic interpolation,
type conversions, etc.):
>>> p['two']['num']
'1'
>>> p['two'].getint('num')
1
>>> p['two']['str'] = 'bool is %(bool)s'
>>> p['two']['str']
'bool is true'
>>> p['two']['bool'] = 'false'
>>> p['two']['str']
'bool is false'
Because the section proxy object follows the dict API very closely, it's
trivial to convert a section to a dict:
>>> dict(p['two'])
{'str': 'bool is false', 'bool': 'false', 'num': '1'}
Note, however, that this sets in stone interpolations and doesn't provide
built-in type conversions.
