如何在Python中将彩色文本输出到终端?
当前回答
您可以使用任何语言提供的shell转义字符。这些转义字符以ESC字符开头,后跟一些参数。
例如,要在终端中输出红色“Hello,World!”字符串:
echo "\e[31m Hello, World! \e[0m"
或者从Python脚本:
print("\e[31m Hello world \e[0m")
此外,我写了一篇关于Escape序列的文章,这可能会帮助您更好地理解这个机制。

对于Windows,除非使用Win32 API,否则无法使用颜色打印到控制台。
对于Linux,它就像使用打印一样简单,转义序列如下:

要使字符像方框一样打印,这实际上取决于控制台窗口使用的字体。磅符号效果很好,但它取决于字体:

输出
为了解决这个问题,我创建了一个简单得让人麻木的程序包,用插值颜色代码打印字符串,称为icolor。
icolor包含两个函数:cformat和cprint,每个函数都包含一个字符串和子字符串,这些子字符串被插值以映射到ANSI转义序列。
from icolor import cformat # there is also cprint
cformat("This is #RED;a red string, partially with a #xBLUE;blue background")
'This is \x1b[31ma red string, partially with a \x1b[44mblue background\x1b[0m'
包括所有ANSI颜色(例如#RED;、#BLUE;等)以及#RESET#粗体;以及其他。
背景色具有x前缀,因此绿色背景将为#xGREEN;。
一个人可以用##逃脱#。
鉴于其简单性,最好的文档可能是代码本身。
它在PYPI上,因此可以使用sudo easy_install icolor。
使用pyfancy。这是一种在终端中进行颜色处理的简单方法!
例子:
print(pyfancy.RED + "Hello Red" + pyfancy.END)
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。
