python_log

a simple encapsulation of logging module to provide a more convenient interface to write log.The log will both print to stdout and write to log file. It provides a more flexible way to set the log actions, and also very simple. See examples showed below:

Example 1: Use default settings

import log
log = log.Log(cmdlevel='info')
log.debug('hello, world')
log.info('hello, world')
log.error('hello, world')
log.critical('hello, world')

Result: Print all log messages to file, and only print log whose level is greater than ERROR to stdout. The log file is located in 'xxx.log' if the module name is xxx.py. The default log file handler is size-rotated, if the log file's size is greater than 20M, then it will be rotated.

Example 2: Use set_logger to change settings

# Change limit size in bytes of default rotating action
log.set_logger(limit = 10240) # 10M

# Use time-rotated file handler, each day has a different log file, see
# logging.handlers.TimedRotatingFileHandler for more help about 'when'
log.set_logger(when = 'D', limit = 1)

# Use normal file handler (not rotated)
log.set_logger(backup_count = 0)

# File log level set to INFO, and stdout log level set to DEBUG
log.set_logger(cmdlevel = 'DEBUG', filelevel = 'INFO')

# Change default log file name and log mode
log.set_logger(filename = 'yyy.log', mode = 'w')

# Change default log formatter
log.set_logger(cmdfmt = '[%(levelname)s] %(message)s')
