How to use the configparser.SafeConfigParser function in configparser

Writes 'value' on 'key' to the configuration file given in
        'filepath'. Configuration parameter in 'key' must follow the schema
        <section>.<option> .

        :param key: key to set
        :param value: value to set
        :param filepath: configuration file
        """
        if not filepath:
            raise RuntimeError("Configuration file not given")

        if not self.__check_config_key(key):
            raise RuntimeError("%s parameter does not exists or cannot be set" % key)

        config = configparser.SafeConfigParser()

        if os.path.isfile(filepath):
            config.read(filepath)

        section, option = key.split('.')

        if section not in config.sections():
            config.add_section(section)

        try:
            config.set(section, option, value)
