这个答案试图通过使用正则表达式为文本块中的关键字着色来扩展将着色文本写入终端的概念。

这个答案还使用了Python库Rich，在前面的问题答案中简要介绍了它。在这个答案中，我使用函数rich.color.ANSI_color_NAMES获取一个随机的颜色列表，用于突出显示预定义的搜索项。

            combined_string = (combined_string + current_string)

以下是上述代码的打印输出：

我创建了两个用于为文本着色的GIST。

彩色文本终端输出彩色文本HTML输出

您可以使用Clint：

from clint.textui import colored
print colored.red('some warning message')
print colored.green('nicely done!')

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。

感谢@qubodup

还有Python termcolor模块。用法很简单：

from termcolor import colored

print colored('hello', 'red'), colored('world', 'green')

或者在Python 3中：

print(colored('hello', 'red'), colored('world', 'green'))

然而，对于游戏编程和你想做的“彩色方块”来说，它可能不够复杂。。。

要使ANSI代码在windows上运行，请首先运行

os.system('color')

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

Coloredlogs包

日志记录库

一个更简单的选择是使用termcolor包中的cprint函数。

它还支持%s，%d格式的打印：

结果可能取决于终端，因此请查看软件包文档的“终端财产”部分。
