colorlog Description

colorlog is a formatter for use with Python's logging module.It allows colors to be placed in the format string, which is mostly useful when paired with a StreamHandler that is outputting to a terminal. This is accomplished by added a set of terminal color codes to the record before it is used to format the string.UsageColoredFormatter requires at minumum a format string, and takes two options - reset (implictly add a reset code at the end of message strings, defaults to true) and color_levels (a mapping of record level names to color names, defaults to colorlog.DEFAULT_COLOR_LEVELS).from colorlog import ColoredFormatterformatstring = "%(bg_level)s%(levelname)-8s%(reset)s %(blue)%(message)s"levels = { 'DEBUG': 'cyan', 'INFO': 'green', 'WARNING': 'yellow', 'ERROR': 'red', 'CRITICAL': 'red',}formatter = ColoredFormatter(formatstring, reset=True, color_levels=levels)The formatter can then be used in a normal logging setup.CodesThe following values are made availible for use in the format string:- fg_{colorname}, bg_{colorname}: Foreground and background colors. The colors names are black, red, green, yellow, blue, purple, cyan and white.- bold: Bold output.- reset: Clear all formatting (both foreground and background colors).- fg_level, bg_level: Return the color associated with the records level (from color_levels).Product's homepage
