Logging facility for python

Initialization

Import library

  • Create a new .py file
import AppLogger

Create a new object

logger = AppLogger.Logger("nameoflog", 'separator', 'extension' )

Where 'nameoflog' can be anything, eg. audit, test.

It will automatically create a new folder in current directory named nameoflog_logs

And the log name in that directory will be called 'nameoflog'_date.log

Usage Example

It can log right before the action is happening.

Or you may put it after, if you so desire.

import AppLogger
import time

logger = AppLogger.Logger("audit")

def my_sleeper_func():
    print ("This function sleeps for 5 seconds")
    logger.write (action="SLEEP", data="5_seconds")
    time.sleep(5)

def my_printer_func():
    print ("This function prints text for 10 iterations")
    for counter in range (1,11):
        logger.write(action="COUNT_TEXT", data=('count_to_(%d)' % counter))
        print (counter)

my_sleeper_func()
my_printer_func()

my_sleeper_func

Here, we have a function that is sleeping for 5 seconds.

The first variable will be an action, where we say that the action is a sleep.

The second variable will be data, where we can put more details about the action.

my_printer_func

Here, we are printing text by looping from 1 to 10.

action is used to show that we are simply doing a "COUNT_TEXT"

data is used to print a text and log the variable counter for each iteration !

This is useful if you want to know how the variables are changing and to log that as well.

Log output

log name here will be: audit_logs/audit_25022021.log
