如何在Python中将彩色文本输出到终端?


当前回答

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。

这里有一种更有效的方法。

# Colours
pure_red = "\033[0;31m"
dark_green = "\033[0;32m"
orange = "\033[0;33m"
dark_blue = "\033[0;34m"
bright_purple = "\033[0;35m"
dark_cyan = "\033[0;36m"
dull_white = "\033[0;37m"
pure_black = "\033[0;30m"
bright_red = "\033[0;91m"
light_green = "\033[0;92m"
yellow = "\033[0;93m"
bright_blue = "\033[0;94m"
magenta = "\033[0;95m"
light_cyan = "\033[0;96m"
bright_black = "\033[0;90m"
bright_white = "\033[0;97m"
cyan_back = "\033[0;46m"
purple_back = "\033[0;45m"
white_back = "\033[0;47m"
blue_back = "\033[0;44m"
orange_back = "\033[0;43m"
green_back = "\033[0;42m"
pink_back = "\033[0;41m"
grey_back = "\033[0;40m"
grey = '\033[38;4;236m'
bold = "\033[1m"
underline = "\033[4m"
italic = "\033[3m"
darken = "\033[2m"
invisible = '\033[08m'
reverse_colour = '\033[07m'
reset_colour = '\033[0m'
grey = "\x1b[90m"

用户手册

reverseColor表示您反转刚刚选择的颜色,但处于高亮模式(默认为白色)。pink_back(green_back等…带有back的)表示它以粉色突出显示(基于名称)。reset_colour重置颜色(详见图1)。

我相信我不需要解释太多,因为它列在变量名中。

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.")

答案是Python中所有跨平台着色的Colorama。

它支持Python 3.5+以及Python 2.7。

截至2021 1月,这一数字仍保持不变。

示例代码:

from colorama import init as colorama_init
from colorama import Fore
from colorama import Style

colorama_init()

print(f"This is {Fore.GREEN}color{Style.RESET_ALL}!")
