Python ConfigParser and ini reading

My current project reads a lot of data from multiple .ini files, and needs to have more than one accessible at a time. I have put together this class to handle the ini-reading, and I thought it might have broader utility for Panda users. Note that the code is derived from a Panda example (apparently incomplete and not linked as a dowload), found here:

class iniReader(object):
    Modified from:
    Functions to load and read configuration from an ini file.
    import ConfigParser # For the .ini reader
    Class object to read and store multiple ini files.
    self.ini = iniReader()
    self.ini.load(os.path.join(self.paths.dirname, self.paths.settings),"settings")
    numcastles = self.ini.readInteger("castles", "count", 5)
    def __init__(self):        
        self.current_ini = None

    def load(self, ini_path, name):
        """Load submitted ini at path to __dict__, using name (string) as key"""
        config_parser = ConfigParser.ConfigParser()        
        self.__dict__[name] = {}
        self.current_ini = self.__dict__[name]
        for section in config_parser.sections():
            self.current_ini[section] = {}            
            for option in config_parser.options(section):
                self.current_ini[section][option] = config_parser.get(section, option)

    def __getitem__(self, name):
        return self.__dict__[name]

    def set_current(self, name):
        """Set the current ini dict to read, by name (string)"""
        if name in self.__dict__:
            self.current_ini = self.__dict__[name]

    def has_section(self, section):
        """Verify that current ini dict has a key for submitted selection"""
        if section in self.current_ini.keys():
            return True
        return False

    def readString(self, section, option, default):
        """Return ini data from dict as string, with default"""        
            return str(self.current_ini[section][option])
        except KeyError:
            return default

    def readInteger(self, section, option, default):
        """Return ini data from dict as integer, with default"""
            return int(self.current_ini[section][option])
        except KeyError:
            return default

    def readFloat(self, section, option, default):
        """Return ini data from dict as float, with default""" 
            return float(self.current_ini[section][option])
        except KeyError:
            return default

    def clear(self, name):
        """Clear the ini listing with the submitted name (string)"""
        if name in self.__dict__:
            if self.__dict__[name] == self.current_ini:
                self.current_ini = None
            self.__dict__[name] = None
            del self.__dict__[name]
