如何在Python中将彩色文本输出到终端?


当前回答

我建议这个新图书馆Printy。他们刚刚发布了版本1.2.0作为跨平台库。

过来看:GitHub上的Printy

它基于标志,所以你可以做类似的事情

from printy import printy

# With global flags, this will apply a bold (B) red (r) color and an underline (U) to the whole text
printy("Hello, World!", "rBU")

# With inline formats, this will apply a dim (D)
#blue (b) to the word 'Hello' and a stroken (S)
#yellow (y) to the word 'world', and the rest will remain as the predefined format
printy("this is a [bD]Hello@ [yS]world@ text")

根据乔尔德的回答,这简直太简单了:

class PrintInColor:
    RED = '\033[91m'
    GREEN = '\033[92m'
    YELLOW = '\033[93m'
    LIGHT_PURPLE = '\033[94m'
    PURPLE = '\033[95m'
    END = '\033[0m'

    @classmethod
    def red(cls, s, **kwargs):
        print(cls.RED + s + cls.END, **kwargs)

    @classmethod
    def green(cls, s, **kwargs):
        print(cls.GREEN + s + cls.END, **kwargs)

    @classmethod
    def yellow(cls, s, **kwargs):
        print(cls.YELLOW + s + cls.END, **kwargs)

    @classmethod
    def lightPurple(cls, s, **kwargs):
        print(cls.LIGHT_PURPLE + s + cls.END, **kwargs)

    @classmethod
    def purple(cls, s, **kwargs):
        print(cls.PURPLE + s + cls.END, **kwargs)

那么就

PrintInColor.red('hello', end=' ')
PrintInColor.green('world')

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

Asciicast:

打印一个开始颜色/样式的字符串,然后是字符串,然后以'\x1b[0m'结束颜色/样式更改:

print('\x1b[6;30;42m' + 'Success!' + '\x1b[0m')

使用以下代码获取shell文本的格式选项表:

def print_format_table():
    """
    prints table of formatted text format options
    """
    for style in range(8):
        for fg in range(30,38):
            s1 = ''
            for bg in range(40,48):
                format = ';'.join([str(style), str(fg), str(bg)])
                s1 += '\x1b[%sm %s \x1b[0m' % (format, format)
            print(s1)
        print('\n')

print_format_table()

使用pyfancy。这是一种在终端中进行颜色处理的简单方法!

例子:

print(pyfancy.RED + "Hello Red" + pyfancy.END)

如果你正在编程一个游戏,也许你想改变背景颜色,只使用空格?例如:

print " "+ "\033[01;41m" + " " +"\033[01;46m"  + "  " + "\033[01;42m"
