如何在Python中将彩色文本输出到终端?
当前回答
我创建了一个项目(控制台颜色),并已将其发布到PyPI。
你可以抛出pip安装控制台颜色来安装它。
我用斯芬克斯写了文档,读了文档,看这里。
你可以从Googlecolab获得更多的例子。
我仍然发布了一些示例来吸引用户点击上面的链接:
# cprint is something like below
# cprint(text: str, fore: T_RGB = None, bg: T_RGB = None, style: Style = '')
# where T_RGB = Union[Tuple[int, int, int], str] for example. You can input (255, 0, 0) or '#ff0000' or 'ff0000'. They are OK.
# The Style you can input the ``Style.`` (the IDE will help you to choose what you wanted)
# from console_color import RGB, Fore, Style, cprint, create_print
from console_color import *
cprint("Hello, World!", RGB.RED, RGB.YELLOW, Style.BOLD+Style.URL+Style.STRIKE)
cprint("Hello, World!", fore=(255, 0, 0), bg="ffff00", style=Style.BOLD+Style.URL+Style.STRIKE)
当然,您不必输入所有参数。您可以只添加所需的属性。
老实说,这个项目并不特别。它只使用f“\033[{target};2;{r};{g};{b}m{text}{style}”其中target是38或48,text是您的输入字符串,style是“\33[0m',“\33[1m'…”\033[9m'。
我只是让它易于使用(至少对我来说)。
其他回答
打印一个开始颜色/样式的字符串,然后是字符串,然后以'\x1b[0m'结束颜色/样式更改:
print('\x1b[6;30;42m' + 'Success!' + '\x1b[0m')
使用以下代码获取shell文本的格式选项表:
def print_format_table():
"""
prints table of formatted text format options
"""
for style in range(8):
for fg in range(30,38):
s1 = ''
for bg in range(40,48):
format = ';'.join([str(style), str(fg), str(bg)])
s1 += '\x1b[%sm %s \x1b[0m' % (format, format)
print(s1)
print('\n')
print_format_table()

当我在寻找如何为日志上色时,我被谷歌感动了:

安装
pip install coloredlogs
用法
最小使用量:
import logging
import coloredlogs
coloredlogs.install() # install a handler on the root logger
logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')
结果如下:
从消息级调试开始:
import logging
import coloredlogs
coloredlogs.install(level='DEBUG') # install a handler on the root logger with level debug
logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')
结果如下:
隐藏库中的邮件:
import logging
import coloredlogs
logger = logging.getLogger(__name__) # get a specific logger object
coloredlogs.install(level='DEBUG') # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger) # pass a specific logger object
logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')
结果如下:
设置日志消息格式:
import logging
import coloredlogs
logger = logging.getLogger(__name__) # get a specific logger object
coloredlogs.install(level='DEBUG') # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger) # pass a specific logger object
coloredlogs.install(
level='DEBUG', logger=logger,
fmt='%(asctime)s.%(msecs)03d %(filename)s:%(lineno)d %(levelname)s %(message)s'
)
logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')
结果如下:
可用的格式属性:
%(asctime)s-发出日志记录调用时,作为人类可读字符串的时间%(created)f-发出日志调用时的浮点时间%(filename)s-文件名%(funcName)s-包含日志记录调用的函数的名称%(hostname)s-系统主机名%(levelname)s-文本日志记录级别%(levelno)s-整数日志记录级别%(lineno)d-发出记录调用的行号%(message)s-传递给日志记录调用的消息(与%(msg)s相同)%(module)s—发出日志记录调用的不带扩展名的文件名%(毫秒)d-发出日志调用的毫秒部分%(msg)s-传递给日志记录调用的消息(与%(Message)s相同)%(name)s-记录器名称%(pathname)s—包含日志记录调用的文件的完整路径名%(process)d-进程ID%(processName)s-进程名称%(programname)s-系统程序名%(relativeCreated)d-发出日志调用时的时间(以毫秒为单位),相对于加载日志模块的时间%(thread)d-线程ID%(threadName)s-线程名称%(username)s-系统用户名

基于joeld的答案,使用https://pypi.python.org/pypi/lazyme 管道安装-U lazyme:
from lazyme.string import color_print
>>> color_print('abc')
abc
>>> color_print('abc', color='pink')
abc
>>> color_print('abc', color='red')
abc
>>> color_print('abc', color='yellow')
abc
>>> color_print('abc', color='green')
abc
>>> color_print('abc', color='blue', underline=True)
abc
>>> color_print('abc', color='blue', underline=True, bold=True)
abc
>>> color_print('abc', color='pink', underline=True, bold=True)
abc

使用新的格式化程序对color_print进行一些更新,例如:
>>> from lazyme.string import palette, highlighter, formatter
>>> from lazyme.string import color_print
>>> palette.keys() # Available colors.
['pink', 'yellow', 'cyan', 'magenta', 'blue', 'gray', 'default', 'black', 'green', 'white', 'red']
>>> highlighter.keys() # Available highlights.
['blue', 'pink', 'gray', 'black', 'yellow', 'cyan', 'green', 'magenta', 'white', 'red']
>>> formatter.keys() # Available formatter,
['hide', 'bold', 'italic', 'default', 'fast_blinking', 'faint', 'strikethrough', 'underline', 'blinking', 'reverse']
注意:斜体、快速闪烁和删除线可能不适用于所有终端,也不适用于Mac和Ubuntu。
例如。,
>>> color_print('foo bar', color='pink', highlight='white')
foo bar
>>> color_print('foo bar', color='pink', highlight='white', reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', bold=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True, reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', underline=True, reverse=True)
foo bar

我是Python新手,每次我发现像这样的主题时都很兴奋。但这次(突然)我觉得我有话要说。尤其是因为几分钟前,我在Python中发现了一件令人惊叹的事情(至少对我来说是这样):
上下文管理器
from contextlib import contextmanager
# FORECOLOR
BLACKFC,REDFC,GREENFC,YELLOWFC,BLUEFC = '38;30m','38;31m','38;32m','38;33m','38;34m'
# BACKGOUND
BLACKBG,REDBG,GREENBG,YELLOWBG,BLUEBG = '48;40m','48;41m','48;42m','48;43m','48;44m'
@contextmanager
def printESC(prefix, color, text):
print("{prefix}{color}{text}".format(prefix=prefix, color=color, text=text), end='')
yield
print("{prefix}0m".format(prefix=prefix))
with printESC('\x1B[', REDFC, 'Colored Text'):
pass
实例
或者就像这样:
# FORECOLOR
BLACKFC,REDFC,GREENFC,YELLOWFC,BLUEFC = '38;30m','38;31m','38;32m','38;33m','38;34m'
# BACKGOUND
BLACKBG,REDBG,GREENBG,YELLOWBG,BLUEBG = '48;40m','48;41m','48;42m','48;43m','48;44m'
def printESC(prefix, color, text):
print("{prefix}{color}{text}".format(prefix=prefix, color=color, text=text), end='')
print("{prefix}0m".format(prefix=prefix))
printESC('\x1B[', REDFC, 'Colored Text')
