5.7 ConfigParser -- Configuration file parser

This module defines the class ConfigParser. The ConfigParser class implements a basic configuration file parser language which provides a structure similar to what you would find on Microsoft Windows INI files. You can use this to write Python programs which can be customized by end users easily.

The configuration file consists of sections, lead by a "[section]" header and followed by "name: value" entries, with continuations in the style of RFC 822; "name=value" is also accepted. Note that leading whitespace is removed from values. The optional values can contain format strings which refer to other values in the same section, or values in a special DEFAULT section. Additional defaults can be provided upon initialization and retrieval. Lines beginning with "#" or ";" are ignored and may be used to provide comments.

For example:

foodir: %(dir)s/whatever

would resolve the "%(dir)s" to the value of "dir" ("frob" in this case). All reference expansions are done on demand.

Default values can be specified by passing them into the ConfigParser constructor as a dictionary. Additional defaults may be passed into the get() method which will override all others.

ConfigParser ([defaults])
Return a new instance of the ConfigParser class. When defaults is given, it is initialized into the dictionary of intrinsic defaults. They keys must be strings, and the values must be appropriate for the "%()s" string interpolation. Note that __name__ is an intrinsic default; its value is the section name, and will override any value provided in defaults.

Exception raised when a specified section is not found.

Exception raised when multiple sections with the same name are found, or if add_section() is called with the name of a section that is already present.

Exception raised when a specified option is not found in the specified section.

Exception raised when problems occur performing string interpolation.

Exception raised when string interpolation cannot be completed because the number of iterations exceeds MAX_INTERPOLATION_DEPTH.

Exception raised when attempting to parse a file which has no section headers.

Exception raised when errors occur attempting to parse a file.

The maximum depth for recursive interpolation for get() when the raw parameter is false. Setting this does not change the allowed recursion depth.
