How to display with 256 colors

Your can choose the color that your like with 'Color' type

>>> from sheen import Str, Color
>>> Color.palette()  # Reference color code
>>>
>>> Color.rgb(222)('render font color with rgb')
>>> Color.RGB(123)('render background color with RGB')
>>> 
>>> Color.rgb([255,200,190])('render font color with rgb')
>>> Color.RGB([150,120,250])('render background color with RGB')
>>>
>>> DIYcolor = Color.rgb(222) | Color.RGB(123) | Str.Underline
>>> DIYcolor("It's my color style")
>>>
>>> text = Str.Underline('Use slice to modification color')
>>> text[:] = Color.rgb(222)
>>> text[-3:-5] = Color.RGB(123)
>>> text

It's said that 256 colors can be valid in the terminal
but maybe invalid in the IDE

How to config Multicolored logging

Sheen has been build-in scheme, which can prints different colored logs based on log level:

As you can see, sheen only takes 5 lines to complete
the configuration of the Multicolored logging

You can design 'Formatter', to get color scheme which belong to yourself

import logging
from sheen import Str, ColoredHandler

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)


handle = ColoredHandler()
handle.setFormatter({
    logging.DEBUG: logging.Formatter(fmt=str(Str.blue('%(asctime)s - %(levelname)s | %(message)s')), datefmt='%Y-%m-%d'),
    logging.INFO: Str.magenta('%(asctime)s - %(levelname)s | %(message)s'),
})
logger.addHandler(handle)

logger.debug('debug')
logger.info('info')
logger.warning('warning')
logger.error('error')
logger.critical('critical')

Take it easy, it will be use after rendered as 'str' type
without affecting the logging output speed
