Logger 对象可以使用 addHandler() 方法向自己添加零个或多个处理器对象。作为示例场景,应用程序可能希望将所有日志消息发送到日志文件,将错误或更高的所有日志消息发送到标准输出,以及将所有关键消息发送至一个邮件地址。 此方案需要三个单独的处理器,其中每个处理器负责将特定严重性的消息发送到特定位置。标准库包含很多处理器类型(参见

The log messages have the severity levelDEBUGas well as the wordrootembedded in them, which refers to the level of your Python module. Theloggingmodule can be used with a hierarchy of loggers that have different names, so that you can use a different logger for each of your modules. For...
Return sends a specified value back to its caller whereas Yield can produce a sequence of values. We should use yield when we want to iterate over a sequence, but don't want to store the entire sequence in memory. import sys # for example when reading a large file, we only care about...

json模块和picle模块都有 dumps、dump、loads、load四种方法,而且用法一样。 不同的是json模块序列化出来的是通用格式,其它编程语言都认识,就是普通的字符串, 而picle模块序列化出来的只有python可以认识,其他编程语言不认识的,表现为乱码 不过picle可以序列化函数,但是其他文件想用该函数,在该文件中需要有该文件的定...
