Modules And Frameworks

Logging

Logging module is a standard library used by both the beginners and enterprise level coders. To import the module: 

import logging
There are 5 standard levels indicating the severity of events. * DEBUG 
logging.debug("This is a debug message")
* INFO 
logging.info("This is a info message")
* WARNING 
logging.warning("This is a warning message")
* ERROR 
logging.error("This is a error message")
* CRITICAL 
logging.critical("This is a critical message")

BASIC CONFIGURATION

Basic configuration is a method that is used to configure the logging. The parameters are : * level ~ The root logger set the severity level * filename ~ Name of the file * filemode ~ The file is opened with the specified mode , default is append mode * format ~ Format of the log message

Examples

  1. To log date and time info : ``` py linenums = "1"

logging configuration

logging.basicConfig(level = logging.INFO , format = '%(asctime)s - %(message)s')

logging

logging.info("User logged in") 

Output :
```2023-08-14 14:41:11,200 - User logged in```

2. To change the format of the date we use `datefmt` attribute :
``` py linenums = "1"
logging.basicConfig(level = logging.INFO,format = '%(asctime)s - %(message)s', datefmt = "%d-%b-%y %H:%M:%S")
logging.info("User logged out")
Output : 14-Aug-23 14:42:24 - User logged out
