如何在Python中将彩色文本输出到终端?
当前回答
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')

我有一个叫做colorist的图书馆。这非常简单。
以下是一些示例:
from colorit import *
# Use this to ensure that ColorIt will be usable by certain command line interfaces
# Note: This clears the terminal
init_colorit()
# Foreground
print(color("This text is red", Colors.red))
print(color("This text is orange", Colors.orange))
print(color("This text is yellow", Colors.yellow))
print(color("This text is green", Colors.green))
print(color("This text is blue", Colors.blue))
print(color("This text is purple", Colors.purple))
print(color("This text is white", Colors.white))
# Background
print(background("This text has a background that is red", Colors.red))
print(background("This text has a background that is orange", Colors.orange))
print(background("This text has a background that is yellow", Colors.yellow))
print(background("This text has a background that is green", Colors.green))
print(background("This text has a background that is blue", Colors.blue))
print(background("This text has a background that is purple", Colors.purple))
print(background("This text has a background that is white", Colors.white))
# Custom
print(color("This color has a custom grey text color", (150, 150, 150)))
print(background("This color has a custom grey background", (150, 150, 150)))
# Combination
print(
background(
color("This text is blue with a white background", Colors.blue), Colors.white
)
)
# If you are using Windows Command Line, this is so that it doesn't close immediately
input()
这为您提供了:
值得注意的是,这是跨平台的,已经在Mac、Linux和Windows上进行了测试。
你可能想试试:https://github.com/SuperMaZingCoder/colorit
coloret现在可以与PyPi一起安装了!您可以在Windows上使用pipinstall-color-it安装它,在macOS和Linux上使用pip3 install-color-it安装它。
下面是一个诅咒示例:
import curses
def main(stdscr):
stdscr.clear()
if curses.has_colors():
for i in xrange(1, curses.COLORS):
curses.init_pair(i, i, curses.COLOR_BLACK)
stdscr.addstr("COLOR %d! " % i, curses.color_pair(i))
stdscr.addstr("BOLD! ", curses.color_pair(i) | curses.A_BOLD)
stdscr.addstr("STANDOUT! ", curses.color_pair(i) | curses.A_STANDOUT)
stdscr.addstr("UNDERLINE! ", curses.color_pair(i) | curses.A_UNDERLINE)
stdscr.addstr("BLINK! ", curses.color_pair(i) | curses.A_BLINK)
stdscr.addstr("DIM! ", curses.color_pair(i) | curses.A_DIM)
stdscr.addstr("REVERSE! ", curses.color_pair(i) | curses.A_REVERSE)
stdscr.refresh()
stdscr.getch()
if __name__ == '__main__':
print "init..."
curses.wrapper(main)
我编写了一个在Linux、OS X和Windows中处理颜色的模块。它支持所有平台上的所有16种颜色,您可以在不同的时间设置前景和背景颜色,字符串对象可以为len()和.capitalize()等对象提供正常的结果。
https://github.com/Robpol86/colorclass
我创建了一个项目(控制台颜色),并已将其发布到PyPI。
你可以抛出pip安装控制台颜色来安装它。
我用斯芬克斯写了文档,读了文档,看这里。
你可以从Googlecolab获得更多的例子。
我仍然发布了一些示例来吸引用户点击上面的链接:
# cprint is something like below
# cprint(text: str, fore: T_RGB = None, bg: T_RGB = None, style: Style = '')
# where T_RGB = Union[Tuple[int, int, int], str] for example. You can input (255, 0, 0) or '#ff0000' or 'ff0000'. They are OK.
# The Style you can input the ``Style.`` (the IDE will help you to choose what you wanted)
# from console_color import RGB, Fore, Style, cprint, create_print
from console_color import *
cprint("Hello, World!", RGB.RED, RGB.YELLOW, Style.BOLD+Style.URL+Style.STRIKE)
cprint("Hello, World!", fore=(255, 0, 0), bg="ffff00", style=Style.BOLD+Style.URL+Style.STRIKE)
当然,您不必输入所有参数。您可以只添加所需的属性。
老实说,这个项目并不特别。它只使用f“\033[{target};2;{r};{g};{b}m{text}{style}”其中target是38或48,text是您的输入字符串,style是“\33[0m',“\33[1m'…”\033[9m'。
我只是让它易于使用(至少对我来说)。
这个答案试图通过使用正则表达式为文本块中的关键字着色来扩展将着色文本写入终端的概念。
这个答案还使用了Python库Rich,在前面的问题答案中简要介绍了它。在这个答案中,我使用函数rich.color.ANSI_color_NAMES获取一个随机的颜色列表,用于突出显示预定义的搜索项。
