It can not be used by itself (it is an abstract base class) and you will always use one of its derivations: wx.Config or wx.FileConfig. wx.ConfigBase organizes the items in a tree-like structure, modeled after the Unix/Dos filesystem. There are groups that act like directories and entries, key/value pairs that act like files. There is always one current group given by the current path. As in the file system case, to specify a key in the config class you must use a path to it. Config classes also support the notion of the current group, which makes it possible to use relative paths. Keys are pairs \"key_name = value\" where value may be of string, integer floating point or boolean, you can not store binary data without first encoding it as a string. For performance reasons items should be kept small, no more than a couple kilobytes.
