1.3. Logging to a file 另外一种非常常见的情况是在文件中记录日志文件,下面让我们来看一下。注意一定要重新开启一个python解释器,而不要接着上面的代码继续写。 importloggingimportos# 先删除过去的日志文件,否则会追加在后面ifos.path.isfile('./example.log'):print('delete the last example.log') os.re...
logging.basicConfig(filename="test.log", filemode="w", format="%(asctime)s %(name)s:%(levelname)s:%(message)s", datefmt="%d-%M-%Y %H:%M:%S", level=logging.DEBUG) a = 5 b = 0 try: c = a / b except Exception as e: # 下面三种方式三选一,推荐使用第一种 logging.exception(...
3.Logging to a file 一般记录方式是将日志记入文件。 import logging logging.basicConfig(filename='example.log',level=logging.DEBUG) logging.debug('This message should go to the log file') logging.info('So should this') logging.warning('And this, too') print: DEBUG:root:This message should ...
logging.warning('Watch out!') # will print a message to the console logging.info('I told you so') # will not print anything 1.2 将日志写入到一个文件中 import logging import os os.chdir("./") # 日志写入地址 logging.basicConfig(filename='example.log', level=logging.DEBUG) ...
pythonCopy codeimport logging logging.basicConfig(filename='app.log',level=logging.DEBUG,format='%(asctime)s - %(levelname)s - %(message)s') 2. 使用配置文件 对于复杂的应用程序,使用配置文件来配置 logging 更为方便。可以通过fileConfig函数加载配置文件,其中配置文件采用 INI 格式。
前面的日志默认会把日志输出到标准输出流,就是只在命令行窗口输出,程序重启后历史日志没地方找,所以把日志内容永久记录是一个很常见的需求。同样通过配置函数logging.basicConfig可以指定日志输出到什么地方 import logging logging.basicConfig(filename="test.log", level=logging.INFO) ...
importlogging logger=logging.getLogger('xxx')handler=logging.StreamHandler()formatter=logging.Formatter('%(asctime)s %(name)-12s %(levelname)-8s %(message)s')handler.setFormatter(formatter)logger.addHandler(handler)logger.setLevel(logging.DEBUG)logger.debug('This is a %s','test') ...
import logging logging.basicConfig(level=logging.DEBUG) logging.debug('Pythondebug') 三、将信息记录到文件 import logging logging.basicConfig(filename='logging.text', level=logging.DEBUG) logging.debug('It is a debug') logging.info('It is a info') logging.warning('It is a warning') ...
