python logging getlogger

The example in this article describes how Python logging the console and file output logs at the same time. Share to everyone for your reference. Specifically as follows: Python provides a very convenient log module that enables simultaneous output logs to the console and files. ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 #-*-

The Python standard log module uses Handler control log messages to write to different destinations, such as files, streams, messages, sockets, and so on. In addition to the Streamhandler, Filehandler, and Nullhandler definitions in the logging module, the other Handler are defined in the Logging.hangdlers module. These Handler are: Watchedfilehandler, Rotatingfilehandler, Timedrotatingfilehandler, Socketha

The logging Module Interface of python is similar to log4j. It is similar in concept and convenient to use. Logging. config. fileconfig () can be used to describe the log configuration in a file, which simplifies log initialization. Routine: # test.pyimport loggingimport logging.configlogging.config.fileConfig("logging.conf")#create loggerlogger = logging.getLogg

Four weeks five sessions (November 10)First, loggingLog is our key tool to troubleshoot problems, write log records, and when we have problems, you can quickly locate the code range to modify. Python gives us developers a good log module, let's introduce the logging module:First, let's look at an example:Import Logginglogging.debug (' This was debug message ') Logging.info (' This is Info message ') logging

Before using the logging module is just the internet casually searched a post, looked at the approximate method directly used. The problem now is that when you add a handler to a Logger object, you use Streamhandler in the configuration file, and you specify the output to stdout (the default is stderr). And since only one logger and one handler are used in the program, all log levels (INFO,DEBUG,ERROR, etc.) are redirected to a place that is standard
