1、直接上代码吧

import logging

class Logger(object):
    def __init__(self, filename):
        self.filename = filename
    def my_log(self, msg, level):
        my_logger = logging.getLogger()
        my_logger.setLevel('DEBUG')
        format = logging.Formatter('%(asctime)s-%(filename)s-[line:%(lineno)d]-%(name)s-%(levelname)s:%(message)s')
        fh = logging.FileHandler(self.filename, encoding='utf8')
        fh.setLevel('DEBUG')
        fh.setFormatter(format)
        my_logger.addHandler(fh)
        if level == 'DEBUG':
            my_logger.debug(msg)
        elif level == "INFO":
            my_logger.info(msg)
        elif level == 'WARNING':
            my_logger.warning(msg)
        elif level == "ERROR":
            my_logger.error(msg)
        else:
            my_logger.critical(msg)
        my_logger.removeHandler(fh)

    def debug(self, msg):
        self.my_log(msg, 'DEBUG')

    def error(self, msg):
        self.my_log(msg, 'ERROR')

    def info(self, msg):
        self.my_log(msg, 'INFO')

    def warning(self, msg):
        self.my_log(msg, 'WARNING')

    def critical(self, msg):
        self.my_log(msg, 'CRITICAL')


if __name__ == '__main__':
    log = Logger('mylog.log')
    log.debug('hello')
    log.info('world')

2、输出如下

2021-05-11 15:35:25,420-get_log.py-[line:15]-root-DEBUG:hello
2021-05-11 15:35:52,359-get_log.py-[line:15]-root-INFO:world

3、在其他文件直接引入调用即可

from get_log import Logger
log=Logger('mylog.log')#实例化一个对象，目前只需要输入日志路径即可
log.info('hello')
log.debug('wold')
