Question

我想要做的就是对我正在编写的程序使用记录器，并且它在日志中什么也没有写，这是相关的代码片段：

#!/usr/bin/python3.6
import logging

class Excel2csv():
def __init__(self, input=None, output=None ):
    self.process_options(input, output)
    self.create_log_directory()
    self.config_logger()

def config_logger(self):
    logger = os.path.basename(__file__).split(".")[0]
    global logger_location
    logger_location = os.getcwd() + '/log/' + datetime.datetime.now().strftime("%Y%m%d%H%M%S") + '.log'
    print("logger_location:" + logger_location)
    logging.basicConfig(filename=logger_location, format='%(asctime)s %(levelname)s %(message)s')
    self.logger = logging.getLogger(logger)
    self.logger.setLevel(logging.INFO)

def run(self):
    start_time = time.time()

    self.extract2csv()

    stop_time = datetime.datetime.now()
    elapsed_time = stop_time - start_time

    self.logger.info('=============================================================================================')
    self.logger.info('Report for the session')

    self.logger.info('Log location for this session: ' + logger_location)
    self.logger.info('Job/report processed by: ' + getpass.getuser() + ' on host: ' + socket.gethostname())
    self.logger.info('=============================================================================================')
    print('\nDone!')


def run_from_cmd():
    Excel2csv().run()

if __name__ == "__main__":
    Excel2csv().run()

已生成日志文件，但未写入任何内容。

非常感谢您能帮助我解决问题，

定义输出级别：

import logging    
logging.basicConfig(level=logging.INFO,
                        format="[%(levelname)s] [%(asctime)s] %(message)s",
                        datefmt="%y-%m-%d %H:%M:%S")

使用文件时，您可以添加：

formatter = logging.Formatter('[%(levelname)s] [%(asctime)s] %(message)s',"%y-%m-%d %H:%M:%S", "%")
fh = logging.FileHandler("log")
fh.setFormatter(formatter)
logger.addHandler(fh)

为什么记录器什么都不写（python3）？
