Recently wrote a crawler system, need to use the Python logging module, so they learned a bit.The log system in the Python standard library is supported from Python2.3. As long as import logging This module can be used. If you want to develop a log system, you need to output the log to the console and write to the log

Next, let's introduce some common handler:1) logging. StreamhandlerUsing this handler, you can output

First introduce how to find out, the line of the project log is through the logging module to the Syslog, ran for a period of time to find the syslog UDP connection over 8W, yes 8 W. The main logging module is wrong. One of the requirements we had before is to output the current connection information for each connection log, so each connection creates a log instance, assigns a Formatter, and creates a log
