如何将彩色文本打印到终端？

如何在Python中将彩色文本输出到终端？

当前回答

在windows 10中，您可以尝试使用这个小脚本，它用作颜色混合器，红色、绿色和蓝色的值为0-255：

import os

os.system('')


def RGB(red=None, green=None, blue=None,bg=False):
    if(bg==False and red!=None and green!=None and blue!=None):
        return f'\u001b[38;2;{red};{green};{blue}m'
    elif(bg==True and red!=None and green!=None and blue!=None):
        return f'\u001b[48;2;{red};{green};{blue}m'
    elif(red==None and green==None and blue==None):
        return '\u001b[0m'

并调用RGB函数使颜色的任意组合为：

g0 = RGB()
g1 = RGB(0,255,0)
g2 = RGB(0,100,0,True)+""+RGB(100,255,100)
g3 = RGB(0,255,0,True)+""+RGB(0,50,0)

print(f"{g1}green1{g0}")
print(f"{g2}green2{g0}")
print(f"{g3}green3{g0}")

不带参数的RGB（）将清理并将前景/背景颜色设置为默认值。如果您想要黑色，则应将其称为RGB（0,0,0），白色RGB（255255255）。当RGB（0255,0）创建绝对绿色时，RGB（150255150）将生成浅绿色。

这支持背景色和前景色，要将颜色设置为背景色，必须使用bg=True传递，默认情况下为False。

例如：若要将红色设置为背景色，应将其称为RGB（255,0,0，True），但若要选择红色作为字体颜色，则只需将其命名为RGB（255，0,0，False），因为默认情况下bg为False，这将简化为仅将其称之为RGB（25.5,0,0）

您可以使用任何语言提供的shell转义字符。这些转义字符以ESC字符开头，后跟一些参数。

例如，要在终端中输出红色“Hello，World！”字符串：

echo "\e[31m Hello, World! \e[0m"

或者从Python脚本：

print("\e[31m Hello world \e[0m")

此外，我写了一篇关于Escape序列的文章，这可能会帮助您更好地理解这个机制。

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"

在我看来，这是最简单的方法。只要您具有所需颜色的RGB值，这应该可以工作：

def colored(r, g, b, text):
    return f"\033[38;2;{r};{g};{b}m{text}\033[0m"

打印红色文本的示例：

text = 'Hello, World!'
colored_text = colored(255, 0, 0, text)
print(colored_text)

#or

print(colored(255, 0, 0, 'Hello, World!'))

多色文本

text = colored(255, 0, 0, 'Hello, ') + colored(0, 255, 0, 'World')
print(text)

耶！另一个版本

虽然我觉得这个答案很有用，但我做了一些修改。此GitHub Gist是结果

用法

print colors.draw("i'm yellow", bold=True, fg_yellow=True)

此外，还可以包装常用用法：

print colors.error('sorry, ')
