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。
class PrintColored:
DEFAULT = '\033[0m'
# Styles
BOLD = '\033[1m'
ITALIC = '\033[3m'
UNDERLINE = '\033[4m'
UNDERLINE_THICK = '\033[21m'
HIGHLIGHTED = '\033[7m'

HIGHLIGHTED_RED = '\033[41m'
HIGHLIGHTED_GREEN = '\033[42m'
HIGHLIGHTED_YELLOW = '\033[43m'
HIGHLIGHTED_BLUE = '\033[44m'
HIGHLIGHTED_PURPLE = '\033[45m'
HIGHLIGHTED_CYAN = '\033[46m'
HIGHLIGHTED_GREY = '\033[47m'

我编写了一个在Linux、OS X和Windows中处理颜色的模块。它支持所有平台上的所有16种颜色，您可以在不同的时间设置前景和背景颜色，字符串对象可以为len（）和.capitalize（）等对象提供正常的结果。

我能找到的最简单的方法不是使用ANSI转义码，而是使用导入模块colorama中的Fore。看看下面的代码：
from colorama import Fore, Style
print(Fore.MAGENTA + "IZZ MAGENTA BRUH.")
print(Style.RESET_ALL + "IZZ BACK TO NORMALZ.")
与ANSI转义码相比：
print("\u001b[31m IZZ RED (NO MAGENTA ON ANSI CODES).\u001b[0m")
print("BACK TO NORMALZ.")
一些解决方案包括：
fg = lambda text, color: "\33[38;5;" + str(color) + "m" + text + "\33[0m"
bg = lambda text, color: "\33[48;5;" + str(color) + "m" + text + "\33[0m"
def print_six(row, format, end="\n"):
for col in range(6):
color = row*6 + col - 2
if color>=0:
text = "{:3d}".format(color)
print (format(text,color), end=" ")
else:
print(end=" ") # Four spaces
print(end=end)
for row in range(0, 43):
print_six(row, fg, " ")
print_six(row, bg)
print(fg("text", 160))
OR
def colored(r, g, b, text):
return "\033[38;2;{};{};{}m{} \033[38;2;255;255;255m".format(r, g, b, text)
text = 'Hello, World!'
colored_text = colored(255, 0, 0, text)
print(colored_text)
OR
class Color:
COLOR = [f"\33[{i}m" for i in range(44)]
for i in range(44):
print(Color.COLOR[i] + 'text')
可能无法在Windows 10终端或PowerShell窗口上运行，或者在其他情况下可能无法直接运行。
但在插入时，程序开头的这两行可能会有所帮助：
import os
os.system('')
os.system（“”）允许您在终端中打印ANSI代码，根据您的选择对输出进行着色（但可能需要调用其他特定于系统的函数，以便能够在终端中显示彩色文本）。
import click
click.secho('Hello, World!', fg='green')
click.secho('Some more text', bg='blue', fg='white')
click.secho('ATTENTION', blink=True, bold=True)
click（CLI库）有一种非常方便的方式来实现这一点，如果您正在编写命令行工具，无论如何都值得考虑。
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。
