如何在Python中将彩色文本输出到终端?


当前回答

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。

我最终做了这个,我觉得这是最干净的:

formatters = {
    'RED': '\033[91m',
    'GREEN': '\033[92m',
    'END': '\033[0m',
}

print 'Master is currently {RED}red{END}!'.format(**formatters)
print 'Help make master {GREEN}green{END} again!'.format(**formatters)

sty类似于colorama,但它不那么冗长,支持8位和24位(RGB)颜色,支持所有效果(粗体、下划线等),允许您注册自己的样式,是完全类型和高性能的,支持静音,不干扰全局设置,如sys.stdout,真的很灵活,文档很好,等等。。。

示例:

from sty import fg, bg, ef, rs

foo = fg.red + 'This is red text!' + fg.rs
bar = bg.blue + 'This has a blue background!' + bg.rs
baz = ef.italic + 'This is italic text' + rs.italic
qux = fg(201) + 'This is pink text using 8bit colors' + fg.rs
qui = fg(255, 10, 10) + 'This is red text using 24bit colors.' + fg.rs

# Add custom colors:

from sty import Style, RgbFg

fg.orange = Style(RgbFg(255, 150, 50))

buf = fg.orange + 'Yay, Im orange.' + fg.rs

print(foo, bar, baz, qux, qui, buf, sep='\n')

打印:

演示:

一些解决方案包括:

fg = lambda text, color: "\33[38;5;" + str(color) + "m" + text + "\33[0m"
bg = lambda text, color: "\33[48;5;" + str(color) + "m" + text + "\33[0m"

def print_six(row, format, end="\n"):
    for col in range(6):
        color = row*6 + col - 2
        if color>=0:
            text = "{:3d}".format(color)
            print (format(text,color), end=" ")
        else:
            print(end="    ")   # Four spaces
    print(end=end)

for row in range(0, 43):
    print_six(row, fg, " ")
    print_six(row, bg)

print(fg("text", 160))

OR

def colored(r, g, b, text):
    return "\033[38;2;{};{};{}m{} \033[38;2;255;255;255m".format(r, g, b, text)


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

OR

class Color:
    COLOR = [f"\33[{i}m" for i in range(44)]

for i in range(44):
    print(Color.COLOR[i] + 'text')

可能无法在Windows 10终端或PowerShell窗口上运行,或者在其他情况下可能无法直接运行。

但在插入时,程序开头的这两行可能会有所帮助:

import os
os.system('')

os.system(“”)允许您在终端中打印ANSI代码,根据您的选择对输出进行着色(但可能需要调用其他特定于系统的函数,以便能够在终端中显示彩色文本)。

这里有一个快速类,它包装了一个打印功能,可以快速添加颜色,而无需安装其他软件包。

输出

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"
