5.9.1 ConfigParser Objects

`ConfigParser` instances have the following methods:

`defaults`()
  Return a dictionary containing the instance-wide defaults.

`sections`()
  Return a list of the sections available; `DEFAULT` is not included in the list.

`add_section`(section)
  Add a section named section to the instance. If a section by the given name already exists, `DuplicateSectionError` is raised.

`has_section`(section)
  Indicates whether the named section is present in the configuration. The `DEFAULT` section is not acknowledged.

`options`(section)
  Returns a list of options available in the specified section.

`has_option`(section, option)
  If the given section exists, and contains the given option. return 1; otherwise return 0. (New in 1.6)

`read`(filenames)
  Read and parse a list of filenames. If filenames is a string or Unicode string, it is treated as a single filename.

`readfp`(fp[, filename])
  Read and parse configuration data from the file or file-like object in fp (only the `readline()` method is used). If filename is omitted and fp has a `name` attribute, that is used for filename; the default is "`<???>`".

`get`(section, option[, raw[, vars]])
  Get an option value for the provided section. All the "`%`" interpolations are expanded in the return values, based on the defaults passed into the constructor, as well as the options vars provided, unless the raw argument is true.

`getint`(section, option)
  A convenience method which coerces the option in the specified section to an integer.

`getfloat`(section, option)
  A convenience method which coerces the option in the specified section to a floating point number.

`getboolean`(section, option)
  A convenience method which coerces the option in the specified section to a boolean value. Note that the only accepted values for the option are "`0`" and "`1`", any others will raise `ValueError`.

`set`(section, option, value)
  If the given section exists, set the given option to the specified value; otherwise raise `NoSectionError`. (New in 1.6)

`write`(fileobject)
  Write a representation of the configuration to the specified file object. This representation can be parsed by a future `read()` call. (New in 1.6)

`remove_option`(section, option)
  Remove the specified option from the specified section. If the section does not exist, raise `NoSectionError`. If the option existed to be removed, return 1; otherwise return 0. (New in 1.6)

`remove_section`(section)
  Remove the specified section from the configuration. If the section in fact existed, return 1. Otherwise return 0.

`optionxform`(option)
  Transforms the option name option as found in an input file or as passed in by client code to the form that should be used in the internal structures. The default implementation returns a lower-case version of option; subclasses may override this or client code can set an attribute of this name on instances to affect this behavior. Setting this to `str()`, for example, would make option names case sensitive.
