如何在Python中将彩色文本输出到终端?


当前回答

asciimatics为构建文本UI和动画提供了可移植的支持:

#!/usr/bin/env python
from asciimatics.effects import RandomNoise  # $ pip install asciimatics
from asciimatics.renderers import SpeechBubble, Rainbow
from asciimatics.scene import Scene
from asciimatics.screen import Screen
from asciimatics.exceptions import ResizeScreenError


def demo(screen):
    render = Rainbow(screen, SpeechBubble('Rainbow'))
    effects = [RandomNoise(screen, signal=render)]
    screen.play([Scene(effects, -1)], stop_on_resize=True)

while True:
    try:
        Screen.wrapper(demo)
        break
    except ResizeScreenError:
        pass

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!")

我使用for循环生成了一个包含所有颜色的类,将颜色的每个组合迭代到100,然后用Python颜色编写了一个类。复制并粘贴,GPLv2由我执行:

class colors:
    '''Colors class:
    Reset all colors with colors.reset
    Two subclasses fg for foreground and bg for background.
    Use as colors.subclass.colorname.
    i.e. colors.fg.red or colors.bg.green
    Also, the generic bold, disable, underline, reverse, strikethrough,
    and invisible work with the main class
    i.e. colors.bold
    '''
    reset='\033[0m'
    bold='\033[01m'
    disable='\033[02m'
    underline='\033[04m'
    reverse='\033[07m'
    strikethrough='\033[09m'
    invisible='\033[08m'
    class fg:
        black='\033[30m'
        red='\033[31m'
        green='\033[32m'
        orange='\033[33m'
        blue='\033[34m'
        purple='\033[35m'
        cyan='\033[36m'
        lightgrey='\033[37m'
        darkgrey='\033[90m'
        lightred='\033[91m'
        lightgreen='\033[92m'
        yellow='\033[93m'
        lightblue='\033[94m'
        pink='\033[95m'
        lightcyan='\033[96m'
    class bg:
        black='\033[40m'
        red='\033[41m'
        green='\033[42m'
        orange='\033[43m'
        blue='\033[44m'
        purple='\033[45m'
        cyan='\033[46m'
        lightgrey='\033[47m'

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!!

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:

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}!")
