Features

  • Color logging in Terminal and CMD
  • Color logging in Jupyter Notebook and Jupyter Lab
  • Color logging in Kaggle Notebook
  • Color logging in Google Colab Notebook
  • Know which function the logger was called from
  • Know while line number the logger was called from
  • Support logging to a file
  • Simple and clean one-liner
  • Customizable

Installation

$ pip install qlogging

Examples

Logging only to console/notebook:

import qlogging
logger = qlogging.get_logger(level='debug')

logger.debug("This is debug") 
logger.info("This is info")
logger.warning("This is warning")
logger.error("This is an error")
logger.critical("This is a critical")

Output (output format: <time> <function_name>,<line#>| <log_message>):

12:21:37 foo(),3| This is debug 
12:21:37 foo(),4| This is info 
12:21:37 foo(),5| This is warning 
12:21:37 foo(),6| This is an error 
12:21:37 foo(),7| This is a critical 

Logging to console/terminal and a log file (append if log file exists):

import qlogging
logger = qlogging.get_logger(level='debug', logfile='my_log.log')

Logging to console/terminal and a log file (overwrite if log file exists):

import qlogging
logger = qlogging.get_logger(level='debug', logfile='my_log.log', logfilemode='w')

Logging with loggingmode='long' (default is loggingmode='short'):

import qlogging
logger = qlogging.get_logger(level='debug', loggingmode='long')

logger.debug("This is debug") 

Output (output format: <date> <time> | <file_name> | <function_name>,<line#>| <log_message>):

2021-05-18 12:38:22 | <main.py> | <foo()>,4 | This is debug

Easy Customization

Customize your logger based on the following get_logger() function parameters

def get_logger(
    level="info",
    logfile=None,
    logfilemode="a",
    loggingmode="short",
    format_str=None,
    file_format_str=None,
    format_date=None,
    colors=None,
    logger_config=None,
):
    """
    returns Python logging based logger formatted with colors

    :param level: (DEFAULT='info') str of logging level, each str option is mapped to Python logging levels, str options:

    :param loggingmode: (DEFAULT='short') str logging mode to be selected. options:
                        'short': will use short str format ('%(asctime)s %(funcName)s,%(lineno)s| %(message)s') and short date format ('%H:%M:%S')
                        'medium': will use long str format ('%(asctime)s | %(filename)s | %(funcName)s,%(lineno)s | %(message)s') and long date format ('%Y-%m-%d %H:%M:%S')
                        'manual': you need to set :param format_str: and :param format_date: yourself
