logging是模块名。 logging模块是Python内置的标准模块。 内置模块直接导入即可使用,不需要安装。 【导入语法】 import+模块名 【代码示例】 import logging 4. 日志的5种级别 开发者根据事件的重要性对程序日志进行了等级划分。 我们可以通过函数、参数等确定输出的日志等级。
import logging # 常用配置 fmt = "%(asctime)s || %(levelname)-8s || %(filename)s %(lineno)-3d || %(process)d || %(message)s" # 显示格式 dfmt = "%Y-%m-%d %H:%M:%S" # 时间显示格式 logging.basicConfig(filename='demo.log', level=logging.DEBUG, format=fmt, datefmt=dfmt) 结...
