Previously tried to back up switch log with expect with bash script, but because it was serially executed, the device took too long and often made a mistake, resulting in incomplete backups. So on the internet to find Python multi-threading related articles, but the basic is based on the TFTP backup run at the time of the configuration file, not according to the Custom Patrol command to obtain the return re
Python provides log functionality through the logging module, and there is already a lot of detailed information on the use of the logging module, and here is how to use the log function in the actual project.Suppose you want to develop an automated scripting tool, the project structure is as follows, common this package is the implementation of the framework fun

A simple example:
Import Logging
logging.warning (' Watch out! ') # Information will print to console
logging.info (' I told ') # will not print any information because the default level is higher than info
If you deposit the above code in a python file, then run:WARNING:root:Watch out!
Info information does not appear in the console because the default level is warning higher than info.

It is believed that every programmer should know that when using Python to write background tasks, it is often necessary to use an output log to record the state of the program running, and to save the details of the error in case of an error to debug and analyze. The Python logging module is a good helper in this case.
The logging module can specify

Log processing operations may occur in many programming languages, and python is no exception...
Next let's take a look atModule
