I'm using Python's logging module like this:
class InitLogging():
def LogModule(self):
self.Logger = logging.getLogger("_TCP_Logger")
self.Logger.LogLevel = logging.DEBUG
self.Logger.setLevel(self.Logger.LogLevel)
self.fh = logging.FileHandler("Log.txt")
self.fh.level = logging.DEBUG
self.formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)8s')
self.Logger.addHandler(self.fh)
self.Logger.log(logging.INFO,"=====================================")
self.Logger.log(logging.INFO,"Start Logging Module!!")
self.Logger.log(logging.INFO,"=====================================")
self.fh .setFormatter(self.formatter)
self.Logger.log(logging.INFO,"Enrty to Logging Module!!")
class LogMsg(InitLogging):
def Logit(self):
self.LogModule()
self.Logger.log(logging.DEBUG,'This is Debugging Message!!')
self.Logger.log(logging.INFO,"This is Info Message!!")
self.Logger.log(logging.WARNING,"This is WARNING Message!!")
LoggingInstance = LogMsg()
LoggingInstance.Logit()
When I run my code I get the output below in Log.txt:
=====================================
Start Logging Module!!
=====================================
2013-03-20 17:51:35,135 INFO Enrty to Logging Module!!
2013-03-20 17:51:35,135 DEBUG This is Debugging Message!!
2013-03-20 17:51:35,135 INFO This is Info Message!
2013-03-20 17:51:35,135 WARNING This is WARNING Message!!
But I'd like to align messages of different log levels together, producing output like below:
=====================================
Start Logging Module!!
=====================================
2013-03-20 17:51:35,135 INFO Enrty to Logging Module!!
2013-03-20 17:51:35,135 DEBUG This is Debugging Message!!
2013-03-20 17:51:35,135 INFO This is Info Message!
2013-03-20 17:51:35,135 WARNING This is WARNING Message!!
How can I do this?

In Python, the built-in logging module can be used to log events. Log messages can have 5 levels - DEBUG, INGO, WARNING, ERROR and CRITICAL. They can also include traceback information for exceptions. Logs can be especially useful in case of errors to help identify their cause.
There are six log levels in Python; each level is associated with an integer that indicates the log severity: NOTSET=0, DEBUG=10, INFO=20, WARN=30, ERROR=40, and CRITICAL=50.
The message logging facility, when active, writes messages to the log data set containing all data that simulated resources transmit or receive in a specified network.
Logging Levels When you set a logging level in Python using the standard module, you're telling the library you want to handle all events from that level on up. If you set the log level to INFO, it will include INFO, WARNING, ERROR, and CRITICAL messages. NOTSET and DEBUG messages will not be included here. Level.
Add a width to the levelname field in the formatter's format string.
This is left-aligned:
self.formatter = logging.Formatter('%(asctime)s %(levelname)-10s %(message)s')
levelname
