用法

彩色支持所有主要的python版本:2.73.43.53.63.7。< BR> 我们建议使用最新版本的pypi

pip install colorful

彩色不需要任何特殊设置即可使用:

importcolorfulprint(colorful.italic_coral_on_beige('Hello World'))print(colorful.italic&colorful.coral_on_beige|'Hello World')print('{c.italic_coral_on_beige}Hello World{c.reset}'.format(c=colorful))

有关详细信息,请参阅样式A字符串"部分!

颜色模式

如今,终端不仅支持古老的8种ansi颜色,而且通常支持多达1600万种颜色,其中真彩色为2824位。如果他们不支持真正的颜色,他们可能至少支持256 ANSI调色板。

彩色支持以下颜色模式:

默认情况下,彩色尝试自动检测终端支持的最佳颜色模式。有关详细信息,请参阅colored.terminal

但是,有时可以指定应使用什么颜色模式。
彩色提供多种方式来实现此目的:

(1)通过python api全局指定颜色模式
colorful.disable()colorful.use_8_ansi_colors()colorful.use_256_ansi_colors()colorful.use_true_colors()

如果在运行时更改颜色模式,它将立即全局生效。

(2)通过环境变量全局强制颜色模式
COLORFUL_DISABLE=1 python eggs.py  # this process will not use ANY coloringCOLORFUL_FORCE_8_COLORS=1 python eggs.py  # this process will use 8 ANSI colors by defaultCOLORFUL_FORCE_256_COLORS=1 python eggs.py  # this process will use 256 ANSI colors by defaultCOLORFUL_FORCE_TRUE_COLORS=1 python eggs.py  # this process will use true colors by default

(3)通过python api(contextmanager)在本地指定颜色模式
withcolorful.with_8_ansi_colors()asc:print(c.italic_coral_on_beige('Hello world'))withcolorful.with_256_ansi_colors()asc:print(c.italic_coral_on_beige('Hello world'))withcolorful.with_true_colors()asc:print(c.italic_coral_on_beige('Hello world'))

调色板

colored的python api基于颜色名称,如colored.bold_white_on_black('hello')。在运行时,这些颜色名被转换成使用中的颜色模式支持的适当ansi escape code序列。但是,所有颜色名都注册在调色板中,这基本上是颜色名与其对应的rgb值之间的映射。非常像这样:

color_palette_example={'black':'#000000','white':'#FFFFFF',}

注意:根据使用的颜色模式,RGB值将减小以适合颜色模式的值域。

默认调色板是x11 rgb.txt调色板-它随colour一起提供,因此,您不必提供自己的调色板。 彩色的附带第二个内置的调色板,名为colornames。 这些颜色来自于颜色名称库的管理列表。 您可以通过colored.setup()方法使用它们,如下所示:

colorful.setup(colorpalette=colorful.COLORNAMES_COLORS)

如果希望将文件中的另一个调色板设置为默认调色板,可以将colornous\u default\u调色板环境变量设置为此文件:

COLORFUL_DEFAULT_COLOR_PALETTE=/usr/share/X11/rgb.txt python spam.py

文件必须是像x11 rgb.txt这样的txt文件,或者是json文件:

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
0

自定义调色板

彩色支持用自定义颜色更新或替换默认调色板。颜色必须指定为RGB十六进制或通道值:

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))

样式

彩色支持一些著名的调色板,在彩色中使用所谓的样式

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))

已经支持以下样式:

<详情>solarized-网站< BR>Solarized colors<详细内容><详情>monokai< BR>Monokai colorsimportcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))3

方法语法可以是:

  • 彩色。<;修饰语>;
  • 彩色。<;修改器1>;<;修改器2>;
  • 彩色。<;fg_color>;
  • 多姿多彩。在背景颜色上
  • 彩色。<;修改器>;<;最终颜色>;
  • 彩色。<;修饰语>;<;背景颜色>;
  • 彩色。<;fg_colors>;&u打开<;bg_color>;
  • 彩色。<;修饰语>;<;fg颜色>;&u on;bg颜色>;

请注意,可以同时指定多个"修饰符"s。

可用的修改器是:

  • 重置(明确地重置传递参数之前的所有样式)
  • 粗体
  • 暗显(不广泛支持)
  • 斜体
  • 下划线
  • 慢速闪烁
  • 快速闪烁
  • 反转(不广泛支持)
  • 隐藏(不广泛支持)
  • 快速通过

可用颜色取决于您使用的调色板。默认情况下,所有x11 rgb.txt颜色都可用。

这种样式方法的返回值类型是colour.colorfulstring。它正确地支持所有str()方法,包括len()

从节名称中的语法可以看出,彩色支持嵌套样式。请参见嵌套样式。

(2)使用&;和

设置字符串样式

彩色的实现\u或\u和协议,将样式和管道字符串组合到其中:

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
4

注意:管道的作用与对样式执行方法调用的作用相同。
所以您可以执行(colored.bold&;colored.red)操作('hello world')

(3)用彩色.格式(string,*args,**kwargs)设置字符串样式

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
5

彩色将用相应的样式替换{c.<;style>;}。不需要将c的彩色对象传递到format()-彩色可以处理这个问题。所有其他格式参数({<;name>;})都必须传递给colored.format()调用asargskwarg

注意:{c.<;style>;}中样式的相同语法、修饰符和颜色可用于(1)使用方法调用设置字符串样式

(4)使用彩色打印字符串。print(*strings,sep='',end='\n',file=sys.stdout,flush=false)

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
6

colored.print()方法接受的参数与python 3.x内置的print()函数相同。

注意:对于python 2,您必须导入打印函数:from uuu future_uuuuu import print_u function

(5)使用str.format()

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
7

注意:在{c.<;style>;}中,样式的语法、修饰符和颜色可以与(1)使用方法调用设置字符串的样式

嵌套样式

彩色的当将参数嵌套的设置为真的时,支持用它的方法调用语法嵌套样式。 如果像下面的第一个示例那样使用str.format()甚至不需要nested=true标志!

以下示例显示了该行为:

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
8

正确支持协议

彩色正确支持样式化字符串上的len()协议(\uu len\uu)。如上所述,当设置字符串样式时,将返回acolored.colorful string对象。此对象返回长度(在调用len()时),因为未样式化字符串将样式化字符串无缝集成到应用程序中。

importcolorful# create a colored string using clever method translationprint(colorful.bold_white('Hello World'))# create a colored string using `str.format()`print('{c.bold}{c.lightCoral_on_white}Hello World{c.reset}'.format(c=colorful))# nest colorsprint(colorful.red('red {0} red'.format(colorful.white('white'))))print(colorful.red('red'+colorful.white(' white ',nested=True)+'red'))# combine styles with stringsprint(colorful.bold&colorful.red|'Hello World')# use true colorscolorful.use_true_colors()# extend default color palettecolorful.update_palette({'mint':'#c5e8c8'})print(colorful.mint_on_snow('Wow, this is actually mint'))# choose a predefined stylecolorful.use_style('solarized')# print the official solarized colorsprint(colorful.yellow('yellow'),colorful.orange('orange'),colorful.red('red'),colorful.magenta('magenta'),colorful.violet('violet'),colorful.blue('blue'),colorful.cyan('cyan'),colorful.green('green'))# directly print with colorscolorful.print('{c.bold_blue}Hello World{c.reset}')# choose specific color mode for one blockwithcolorful.with_8_ansi_colors()asc:print(c.bold_green('colorful is awesome!'))# create and choose your own color paletteMY_COMPANY_PALETTE={'companyOrange':'#f4b942','companyBaige':'#e8dcc5'}withcolorful.with_palette(my_company_palette)asc:print(c.companyOrange_on_companyBaige('Thanks for choosing our product!'))# use f-string (only Python >= 3.6)print(f'{colorful.bold}Hello World')# support for chineseprint(colorful.red('你好'))
