Python logs log _python based on file size

This article describes the python based on file size log logging method, share for everyone to reference. The specific methods are as follows:

Import glob 
Import logging 
import logging.handlers 
log_filename= ' logging_rotatingfile_example.out ' 
# Set up a specific logger the desired output level 
My_logger = Logging.getlogger (' MyLogger ') 
My_logger. Setlevel (logging. DEBUG) 
# ADD The log message handler to the logger 
handler = Logging.handlers.RotatingFileHandler (log_filename,< C9/>maxbytes=20, 
            backupcount=5, 
           ) 
My_logger.addhandler (handler) 
# Log Some messages for 
I In range: 
 my_logger.debug (' i =%d '% i) 
# What files are created 
 logfiles = Glob.glob ('%s* '% log_f ilename) for 
 filename in logfiles: 
  print filename 

This instance can be used to loop log, the first file reached the MaxBytes size, the second file is written.
