Configparser 사용하여 파일 읽기

import configparser

class SystemInfo:
    def get_file_directory():
        return (os.path.dirname(os.path.realpath(__file__)))

class ReadConfig:
    def __init__(self):
        dir = SystemInfo.get_file_directory()
        self.conf_file = dir + '\config.ini'
    
    def load_config(self):
        if os.path.exists(self.conf_file) == False:
            raise Exception('%s file does not exist. \n' % self.conf_file)
        else: 
            config = configparser.ConfigParser()
            config.read(self.conf_file, encoding = 'utf-8')
            print("Load Config : %s" % self.conf_file)
            return config

설정값 가져오기

def main():
    config = ReadConfig.load_config(ReadConfig())
    # 방법1
    SLACK_TOKEN = config.get('SLACK', 'bot_token')
    # 방법2
    SLACK_TOKEN = config['SLACK']['bot_token']

if __name__ == "__main__":
