如何在Python中将彩色文本输出到终端?


当前回答

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.")

您可以使用curses库的Python实现:curses-字符单元显示的终端处理

此外,运行此程序,您将找到您的盒子:

for i in range(255):
    print i, chr(i)

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:

#
class ColorText:
    """
    Use ANSI escape sequences to print colors +/- bold/underline to bash terminal.

    Examples
    --------
    >>> ColorText('HelloWorld').bold()
    >>> ColorText('HelloWorld').blue()
    >>> ColorText('HelloWorld').bold().custom("#bebebe")
    >>> ColorText('HelloWorld').underline().custom('dodgerblue')
    >>> ColorText.demo()

    Notes
    -----
    - execute ColorText.demo() for a printout of colors.
    """

    @classmethod
    def demo(cls):
        """Prints examples of all colors in normal, bold, underline, bold+underline."""
        for color in dir(ColorText):
            if all([color.startswith("_") is False,
                    color not in ["bold", "underline", "demo", "custom"],
                    callable(getattr(ColorText, color))]):
                print(getattr(ColorText(color), color)(),
                      "\t",
                      getattr(ColorText(f"bold {color}").bold(), color)(),

        print(ColorText("Input can also be color hex or R,G,B with ColorText.custom()").bold())
        pass

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)

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")
