Fallback Values

provide fallback values:

.. doctest::

>>> topsecret.get('CompressionLevel', '3')

'9'

provides a custom, more complex interface, maintained for backwards

compatibility. When using this method, a fallback value can be provided via

the ``fallback`` keyword-only argument:

than the first line of the value. Depending on the parser's mode, blank lines

may be treated as parts of multiline values or ignored.

To change this, see :attr:`ConfigParser.SECTCRE`.

Configuration files may include comments, prefixed by specific

of the features.

The most common way to change the way a specific config parser works is to use

* *defaults*, default value: ``None``

the documented default.

Hint: if you want to specify default values for a specific section, use

* *dict_type*, default value: :class:`dict`

* *strict*, default value: ``True``

When set to ``True``, the parser will not allow for any section or option

parsers in new applications.

desirable, users may define them in a subclass or pass a dictionary where each

key is a name of the converter and each value is a callable implementing said

conversion. For instance, passing ``{'decimal': decimal.Decimal}`` would add

other words, it will be possible to write both

``parser_instance.getdecimal('section', 'key', fallback=0)`` and

``parser_instance['section'].getdecimal('key', 0)``.

The :mod:`logging` module provided two kinds of configuration, one style with

function calls for each option or another style driven by an external file saved

to create configurations from JSON or YAML files, nor did they support

incremental configuration, which is needed for specifying logger options from a

command line.

The :mod:`configparser` module was modified to improve usability and

predictability of the default parser and its supported INI syntax. The old

for inline comments is now turned off by default and section or option

duplicates are not allowed in a single configuration source.
