如何在Python中将彩色文本输出到终端?


当前回答

定义开始颜色的字符串和结束颜色的字符串。然后打印文本,开始字符串在前面,结束字符串在结尾。

CRED = '\033[91m'
CEND = '\033[0m'
print(CRED + "Error, does not compute!" + CEND)

这将在Bash和urxvt中使用Zenburn风格的配色方案生成以下内容:

通过实验,我们可以获得更多的颜色:

注意:\33[5m和\33[6m闪烁。

这样我们可以创建一个完整的颜色集合:

CEND      = '\33[0m'
CBOLD     = '\33[1m'
CITALIC   = '\33[3m'
CURL      = '\33[4m'
CBLINK    = '\33[5m'
CBLINK2   = '\33[6m'
CSELECTED = '\33[7m'

CBLACK  = '\33[30m'
CRED    = '\33[31m'
CGREEN  = '\33[32m'
CYELLOW = '\33[33m'
CBLUE   = '\33[34m'
CVIOLET = '\33[35m'
CBEIGE  = '\33[36m'
CWHITE  = '\33[37m'

CBLACKBG  = '\33[40m'
CREDBG    = '\33[41m'
CGREENBG  = '\33[42m'
CYELLOWBG = '\33[43m'
CBLUEBG   = '\33[44m'
CVIOLETBG = '\33[45m'
CBEIGEBG  = '\33[46m'
CWHITEBG  = '\33[47m'

CGREY    = '\33[90m'
CRED2    = '\33[91m'
CGREEN2  = '\33[92m'
CYELLOW2 = '\33[93m'
CBLUE2   = '\33[94m'
CVIOLET2 = '\33[95m'
CBEIGE2  = '\33[96m'
CWHITE2  = '\33[97m'

CGREYBG    = '\33[100m'
CREDBG2    = '\33[101m'
CGREENBG2  = '\33[102m'
CYELLOWBG2 = '\33[103m'
CBLUEBG2   = '\33[104m'
CVIOLETBG2 = '\33[105m'
CBEIGEBG2  = '\33[106m'
CWHITEBG2  = '\33[107m'

以下是生成测试的代码:

x = 0
for i in range(24):
  colors = ""
  for j in range(5):
    code = str(x+j)
    colors = colors + "\33[" + code + "m\\33[" + code + "m\033[0m "
  print(colors)
  x = x + 5

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。

这里有一个简单的函数,我使用它来打印彩色文本消息,而不必记住ANSI代码,而是使用标准RGB元组来定义前景和背景颜色。

def print_in_color(txt_msg, fore_tuple, back_tuple, ):
    # Prints the text_msg in the foreground color specified by fore_tuple with the background specified by back_tuple
    # text_msg is the text, fore_tuple is foreground color tuple (r,g,b), back_tuple is background tuple (r,g,b)
    rf,bf,gf = fore_tuple
    rb,gb,bb = back_tuple
    msg = '{0}' + txt_msg
    mat = '\33[38;2;' + str(rf) + ';' + str(gf) + ';' + str(bf) + ';48;2;' + str(rb) + ';' +str(gb) + ';' + str(bb) + 'm'
    print(msg .format(mat))
    print('\33[0m') # Returns default print color to back to black

# Example of use using a message with variables
fore_color = 'cyan'
back_color = 'dark green'
msg = 'foreground color is {0} and the background color is {1}'.format(fore_color, back_color)
print_in_color(msg, (0,255,255), (0,127,127))

我创建了一个项目(控制台颜色),并已将其发布到PyPI。

你可以抛出pip安装控制台颜色来安装它。

我用斯芬克斯写了文档,读了文档,看这里。

你可以从Googlecolab获得更多的例子。

我仍然发布了一些示例来吸引用户点击上面的链接:

# cprint is something like below
# cprint(text: str, fore: T_RGB = None, bg: T_RGB = None, style: Style = '')
# where T_RGB = Union[Tuple[int, int, int], str] for example. You can input (255, 0, 0) or '#ff0000' or 'ff0000'. They are OK.
# The Style you can input the ``Style.`` (the IDE will help you to choose what you wanted)

# from console_color import RGB, Fore, Style, cprint, create_print
from console_color import *

cprint("Hello, World!", RGB.RED, RGB.YELLOW, Style.BOLD+Style.URL+Style.STRIKE)
cprint("Hello, World!", fore=(255, 0, 0), bg="ffff00", style=Style.BOLD+Style.URL+Style.STRIKE)

当然,您不必输入所有参数。您可以只添加所需的属性。


老实说,这个项目并不特别。它只使用f“\033[{target};2;{r};{g};{b}m{text}{style}”其中target是38或48,text是您的输入字符串,style是“\33[0m',“\33[1m'…”\033[9m'。

我只是让它易于使用(至少对我来说)。

您可以使用Clint:

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

最低等级:

class log:
    f = lambda color: lambda string: print(color + string + "\33[0m")

    black = f("\33[30m")
    red = f("\33[31m")
    green = f("\33[32m")
    yellow = f("\33[33m")
    blue = f("\33[34m")
    magenta = f("\33[35m")
    cyan = f("\33[36m")
    white = f("\33[37m")

# Usage
log.blue("Blue World!")
