Simple Logging Utility

Project description

SimpleLogger is a simple logging utility for Python. I find the default Python logging module powerful, but extremely clunky and difficult to setup quickly. SimpleLogger supports basics such as output redirection, custom logging format, and logging levels.


Log Levels and Threshold:

The current threshold that determines what level of log entries can be seen is set through Logger.set_threshold, passing a constant as the argument. Level constants include DEBUG, INFO, WARNING, ERROR, and CRITICAL. Changing the threshold only affects future entries.

Logging Formats:

Logging formats are set through Logger.set_format, passing a string of valid characters and substitution directives as arguments.

Valid subsitution directives include:




The current time


The current date and time


The current date


The level of the entry


The text to be logged



pip install simplelogger

The Hard Way:

python install


Basic usage::

import simplelogger

# make a new logger that outputs to output_file.log, has a threshold of DEBUG, and the entry format is just the text to be logged
logger = simplelogger.Logger(stream=output_file.log, threshold=simplelogger.DEBUG, format="{text}")"Log at the info level")
logger.warning("Log at the warning level")

if (foo > bar):
    # change the logging threshold to INFO
    # change the format to output the logged text, the date and time, and the time separated by characters
    logger.set_format("{text}: {datetime} - {time}")
