如何在Python中将彩色文本输出到终端？
当前回答
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。
Windows命令提示符和Python IDLE不工作
JupyterLab笔记本确实有效

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：
颜色
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：

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。

输出
您可以使用curses库的Python实现：curses-字符单元显示的终端处理
此外，运行此程序，您将找到您的盒子：
for i in range(255):
print i, chr(i)
如果您正在使用Django：
>>> from django.utils.termcolors import colorize
>>> print colorize("Hello, World!", fg="blue", bg='red',
... opts=('bold', 'blink', 'underscore',))
Hello World!
>>> help(colorize)
快照：
（我通常在runserver终端上使用彩色输出进行调试，所以我添加了它。）
您可以测试它是否安装在您的机器中：$python-c“import django；print django.VERSION”。要安装它，请查看：如何安装django
试试看！！
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')
