The new version of Python logging encapsulation supports simultaneous output to the console, file, and Socket

The logging encapsulation of python is updated. Currently, it supports outputting data to the console, file, and socket at the same time. At the same time, you can clear all the handler of the root logger When configuring config_logging or config_logging_plus, avoid repeated output in some cases.

The usage is simple. You only need to configure logging. The sample code is as follows:

 
ImportLoggingconfigloggingconfig. config_logging (file_name="Log. Log", Log_level ="Noset")
