如何在Python中将彩色文本输出到终端？
当前回答
这里有一个快速类，它包装了一个打印功能，可以快速添加颜色，而无需安装其他软件包。

当我在寻找如何为日志上色时，我被谷歌感动了：
彩色原木
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

考虑到您是否正在编写命令行工具，这是最简单和方便的方法。这种方法可以在所有控制台上的任何地方工作，而无需安装任何花哨的软件包。
要使ANSI代码在Windows上运行，首先，运行os.system（'color'）
import os
os.system('color')
COLOR = '\033[91m' # change it, according to the color need
END = '\033[0m'
print(COLOR + "Hello World" + END) #print a message
exit=input() #to avoid closing the terminal windows
更多颜色：
注意：\33[5m和\33[6m闪烁。

Use ANSI escape sequences to print colors +/- bold/underline to bash terminal.

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
截图：
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
截图：
定义开始颜色的字符串和结束颜色的字符串。然后打印文本，开始字符串在前面，结束字符串在结尾。
CRED = '\033[91m'
CEND = '\033[0m'
print(CRED + "Error, does not compute!" + CEND)
这将在Bash和urxvt中使用Zenburn风格的配色方案生成以下内容：
通过实验，我们可以获得更多的颜色：
注意：\33[5m和\33[6m闪烁。
这样我们可以创建一个完整的颜色集合：
CEND = '\33[0m'
CBOLD = '\33[1m'
CITALIC = '\33[3m'
CURL = '\33[4m'
CBLINK = '\33[5m'
CBLINK2 = '\33[6m'

CBLACK = '\33[30m'
CRED = '\33[31m'
CGREEN = '\33[32m'

CVIOLETBG = '\33[45m'
CBEIGEBG = '\33[46m'
CWHITEBG = '\33[47m'
CGREY = '\33[90m'
CRED2 = '\33[91m'

colors = ""
for j in range(5):
code = str(x+j)
colors = colors + "\33[" + code + "m\\33[" + code + "m\033[0m "
print(colors)
x = x + 5
