幸运的是,Python提供了一种简单的方式来配置将报错信息输出到文件。 下面是一个示例代码,演示了如何将报错信息输出到文件中: importsys# 打开文件,将标准错误重定向到文件sys.stderr=open('error.txt','w')try:# 抛出一个错误raiseException("This is an error message.")exceptExceptionase:# 输出错误信息prin...
exception(message[, *args]) log(log_level, log_message, [*args[, **kwargs]]) Handler对象负责分配合适的log信息(基于log信息的严重程度)到handler指定的目的地.Logger对象可以用addHandler()方法添加零个或多个handler对象到它自身.一个常见的场景是,一个应用可能希望把所有的log信息都发送到一个log文件中...
try,except使用判断异常，try后面的语句发生异常就执行except后的语句，而if，else则只是选择结构。print是输出，return是函数返回某个对象或值，两码事。这些随便找本教程都有讲解的 try
