logging模块简单使用

import logging

def get_logger(level=‘info‘,filename=‘analysis.log‘):
    log_level = {
        ‘debug‘:logging.DEBUG,
        ‘info‘:logging.INFO,
        ‘warning‘:logging.WARNING,
        ‘error‘:logging.ERROR,
        ‘critical‘:logging.CRITICAL
    }
    logger = logging.getLogger(__name__)
    formatter = logging.Formatter(‘"%(asctime)s" "%(filename)s[line:%(lineno)d]" "%(levelname)s" "%(message)s"‘)
    file = os.path.join(‘./‘,filename)
    handler = logging.FileHandler(file, mode=‘a‘)
    level = ‘info‘ if level not in log_level else level
    handler.setLevel(log_level[level])
    handler.setFormatter(formatter)
    logger.addHandler(handler)
    return logger
