print - python termcolor




在颜色的终端打印? (20)

好极了! 另一个版本

而我觉得this答案很有用,我修改了一下。 这Github Gist是结果

用法

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

另外你可以包装常见的用法:

print colors.error('sorry, ')

我如何在Python中输出彩色文本到终端? 代表固体块的最佳Unicode符号是什么?


对于角色

您的终端最可能使用Unicode(通常是UTF-8编码)字符,因此只能选择适当的字体来查看您最喜欢的字符。 Unicode char U + 2588,“Full block”是我建议你使用的那个。

尝试以下操作:

import unicodedata
fp= open("character_list", "w")
for index in xrange(65536):
    char= unichr(index)
    try: its_name= unicodedata.name(char)
    except ValueError: its_name= "N/A"
    fp.write("%05d %04x %s %s\n" % (index, index, char.encode("UTF-8"), its_name)
fp.close()

稍后用您最喜爱的查看器检查文件。

对于颜色

curses是你想要使用的模块。 查看本教程


asciimatics为构建文本UI和动画提供了便携式支持:

#!/usr/bin/env python
from asciimatics.effects import RandomNoise  # $ pip install asciimatics
from asciimatics.renderers import SpeechBubble, Rainbow
from asciimatics.scene import Scene
from asciimatics.screen import Screen
from asciimatics.exceptions import ResizeScreenError


def demo(screen):
    render = Rainbow(screen, SpeechBubble('Rainbow'))
    effects = [RandomNoise(screen, signal=render)]
    screen.play([Scene(effects, -1)], stop_on_resize=True)

while True:
    try:
        Screen.wrapper(demo)
        break
    except ResizeScreenError:
        pass

sty类似于colorama,但它不那么冗长,支持8bit24bit (rgb)颜色,允许你注册你自己的颜色,非常灵活并且有很好的文档记录。 如果您不关心与90年代终端仿真器的兼容性问题,并且喜欢使用新功能,则可以尝试一下。

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 new colors:

fg.orange = ('rgb', (255, 150, 50))

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


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

你可以使用CLINT

from clint.textui import colored
print colored.red('some warning message')
print colored.green('nicely done!')

使用for循环来生成一个包含所有颜色的类,以便将每种颜色组合重复为100,然后用python颜色编写一个类。 按照你的意愿复制和粘贴GPLv2:

class colors:
    '''Colors class:
    reset all colors with colors.reset
    two subclasses fg for foreground and bg for background.
    use as colors.subclass.colorname.
    i.e. colors.fg.red or colors.bg.green
    also, the generic bold, disable, underline, reverse, strikethrough,
    and invisible work with the main class
    i.e. colors.bold
    '''
    reset='\033[0m'
    bold='\033[01m'
    disable='\033[02m'
    underline='\033[04m'
    reverse='\033[07m'
    strikethrough='\033[09m'
    invisible='\033[08m'
    class fg:
        black='\033[30m'
        red='\033[31m'
        green='\033[32m'
        orange='\033[33m'
        blue='\033[34m'
        purple='\033[35m'
        cyan='\033[36m'
        lightgrey='\033[37m'
        darkgrey='\033[90m'
        lightred='\033[91m'
        lightgreen='\033[92m'
        yellow='\033[93m'
        lightblue='\033[94m'
        pink='\033[95m'
        lightcyan='\033[96m'
    class bg:
        black='\033[40m'
        red='\033[41m'
        green='\033[42m'
        orange='\033[43m'
        blue='\033[44m'
        purple='\033[45m'
        cyan='\033[46m'
        lightgrey='\033[47m'

在Windows上,您可以使用模块“win32console”(在某些Python发行版中提供)或模块“ctypes”(Python 2.5及更高版本)访问Win32 API。

要查看支持两种方式的完整代码,请参阅Testoob颜色控制台报告代码

ctypes例子:

import ctypes

# Constants from the Windows API
STD_OUTPUT_HANDLE = -11
FOREGROUND_RED    = 0x0004 # text color contains red.

def get_csbi_attributes(handle):
    # Based on IPython's winconsole.py, written by Alexander Belchenko
    import struct
    csbi = ctypes.create_string_buffer(22)
    res = ctypes.windll.kernel32.GetConsoleScreenBufferInfo(handle, csbi)
    assert res

    (bufx, bufy, curx, cury, wattr,
    left, top, right, bottom, maxx, maxy) = struct.unpack("hhhhHhhhhhh", csbi.raw)
    return wattr


handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
reset = get_csbi_attributes(handle)

ctypes.windll.kernel32.SetConsoleTextAttribute(handle, FOREGROUND_RED)
print "Cherry on top"
ctypes.windll.kernel32.SetConsoleTextAttribute(handle, reset)

如果你使用的是Windows,那么你就去!

# display text on a Windows console
# Windows XP with Python27 or Python32
from ctypes import windll
# needed for Python2/Python3 diff
try:
    input = raw_input
except:
    pass
STD_OUTPUT_HANDLE = -11
stdout_handle = windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
# look at the output and select the color you want
# for instance hex E is yellow on black
# hex 1E is yellow on blue
# hex 2E is yellow on green and so on
for color in range(0, 75):
     windll.kernel32.SetConsoleTextAttribute(stdout_handle, color)
     print("%X --> %s" % (color, "Have a fine day!"))
     input("Press Enter to go on ... ")

如果你正在编程一个游戏,也许你想改变背景颜色并只使用空格? 例如:

print " "+ "\033[01;41m" + " " +"\033[01;46m"  + "  " + "\033[01;42m"

定义一个开始颜色的字符串和一个结束颜色的字符串,然后打印文本,起始字符串在前面,结束字符串在结尾。

CRED = '\033[91m'
CEND = '\033[0m'
print(CRED + "Error, does not compute!" + CEND)

这会在bash产生以下结果,在urxvt使用Zenburn样式的颜色方案:

通过exremintation,我们可以获得更多的颜色:

注意: \33[5m\33[6m闪烁。

这样我们可以创建一个全彩色集合:

CEND      = '\33[0m'
CBOLD     = '\33[1m'
CITALIC   = '\33[3m'
CURL      = '\33[4m'
CBLINK    = '\33[5m'
CBLINK2   = '\33[6m'
CSELECTED = '\33[7m'

CBLACK  = '\33[30m'
CRED    = '\33[31m'
CGREEN  = '\33[32m'
CYELLOW = '\33[33m'
CBLUE   = '\33[34m'
CVIOLET = '\33[35m'
CBEIGE  = '\33[36m'
CWHITE  = '\33[37m'

CBLACKBG  = '\33[40m'
CREDBG    = '\33[41m'
CGREENBG  = '\33[42m'
CYELLOWBG = '\33[43m'
CBLUEBG   = '\33[44m'
CVIOLETBG = '\33[45m'
CBEIGEBG  = '\33[46m'
CWHITEBG  = '\33[47m'

CGREY    = '\33[90m'
CRED2    = '\33[91m'
CGREEN2  = '\33[92m'
CYELLOW2 = '\33[93m'
CBLUE2   = '\33[94m'
CVIOLET2 = '\33[95m'
CBEIGE2  = '\33[96m'
CWHITE2  = '\33[97m'

CGREYBG    = '\33[100m'
CREDBG2    = '\33[101m'
CGREENBG2  = '\33[102m'
CYELLOWBG2 = '\33[103m'
CBLUEBG2   = '\33[104m'
CVIOLETBG2 = '\33[105m'
CBEIGEBG2  = '\33[106m'
CWHITEBG2  = '\33[107m'

以下是生成测试的代码:

x = 0
for i in range(24):
  colors = ""
  for j in range(5):
    code = str(x+j)
    colors = colors + "\33[" + code + "m\\33[" + code + "m\033[0m "
  print(colors)
  x=x+5

建立在@joeld答案上,使用https://pypi.python.org/pypi/lazyme pip install -U lazyme

from lazyme.string import color_print
>>> color_print('abc')
abc
>>> color_print('abc', color='pink')
abc
>>> color_print('abc', color='red')
abc
>>> color_print('abc', color='yellow')
abc
>>> color_print('abc', color='green')
abc
>>> color_print('abc', color='blue', underline=True)
abc
>>> color_print('abc', color='blue', underline=True, bold=True)
abc
>>> color_print('abc', color='pink', underline=True, bold=True)
abc

截图:

用新的格式化程序对color_print进行一些更新,例如:

>>> from lazyme.string import palette, highlighter, formatter
>>> from lazyme.string import color_print
>>> palette.keys() # Available colors.
['pink', 'yellow', 'cyan', 'magenta', 'blue', 'gray', 'default', 'black', 'green', 'white', 'red']
>>> highlighter.keys() # Available highlights.
['blue', 'pink', 'gray', 'black', 'yellow', 'cyan', 'green', 'magenta', 'white', 'red']
>>> formatter.keys() # Available formatter, 
['hide', 'bold', 'italic', 'default', 'fast_blinking', 'faint', 'strikethrough', 'underline', 'blinking', 'reverse']

注意: italicfast blinkingstrikethrough可能无法在所有终端上运行,在Mac / Ubuntu上不起作用。

例如

>>> color_print('foo bar', color='pink', highlight='white')
foo bar
>>> color_print('foo bar', color='pink', highlight='white', reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', bold=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True, reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', underline=True, reverse=True)
foo bar

我已将@joeld答案包装到具有全局函数的模块中,我可以在代码中的任何位置使用它。

文件:log.py

HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
BOLD = "\033[1m"

def disable():
    HEADER = ''
    OKBLUE = ''
    OKGREEN = ''
    WARNING = ''
    FAIL = ''
    ENDC = ''

def infog( msg):
    print OKGREEN + msg + ENDC

def info( msg):
    print OKBLUE + msg + ENDC

def warn( msg):
    print WARNING + msg + ENDC

def err( msg):
    print FAIL + msg + ENDC

使用方法如下:

 import log
    log.info("Hello World")
    log.err("System Error")

我很惊讶没有人提到Python termcolor模块 。 用法很简单:

from termcolor import colored

print colored('hello', 'red'), colored('world', 'green')

但是,对于游戏编程和你想要做的“彩色块”,它可能不够复杂......


我最终这样做,我觉得它是最干净的:

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)

我编写了一个在Linux / OSX / 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色和背景色,而字符串对象可为len()和.capitalize()等功能提供理想的结果。

https://github.com/Robpol86/colorclass


打印一个字符串,开始一个颜色/样式,然后是字符串,然后用'\x1b[0m'结束颜色/样式更改:

print('\x1b[6;30;42m' + 'Success!' + '\x1b[0m')

使用以下代码获取shell文本的格式选项表:

def print_format_table():
    """
    prints table of formatted text format options
    """
    for style in range(8):
        for fg in range(30,38):
            s1 = ''
            for bg in range(40,48):
                format = ';'.join([str(style), str(fg), str(bg)])
                s1 += '\x1b[%sm %s \x1b[0m' % (format, format)
            print(s1)
        print('\n')

print_format_table()

Light-On-Dark示例(完整)

暗光示例(部分)


根据@ joeld的回答,这很愚蠢简单

class PrintInColor:
    RED = '\033[91m'
    GREEN = '\033[92m'
    YELLOW = '\033[93m'
    LIGHT_PURPLE = '\033[94m'
    PURPLE = '\033[95m'
    END = '\033[0m'

    @classmethod
    def red(cls, s, **kwargs):
        print(cls.RED + s + cls.END, **kwargs)

    @classmethod
    def green(cls, s, **kwargs):
        print(cls.GREEN + s + cls.END, **kwargs)

    @classmethod
    def yellow(cls, s, **kwargs):
        print(cls.YELLOW + s + cls.END, **kwargs)

    @classmethod
    def lightPurple(cls, s, **kwargs):
        print(cls.LIGHT_PURPLE + s + cls.END, **kwargs)

    @classmethod
    def purple(cls, s, **kwargs):
        print(cls.PURPLE + s + cls.END, **kwargs)

然后就是了

PrintInColor.red('hello', end=' ')
PrintInColor.green('world')

试试这个简单的代码

def prRed(prt): print("\033[91m {}\033[00m" .format(prt))
def prGreen(prt): print("\033[92m {}\033[00m" .format(prt))
def prYellow(prt): print("\033[93m {}\033[00m" .format(prt))
def prLightPurple(prt): print("\033[94m {}\033[00m" .format(prt))
def prPurple(prt): print("\033[95m {}\033[00m" .format(prt))
def prCyan(prt): print("\033[96m {}\033[00m" .format(prt))
def prLightGray(prt): print("\033[97m {}\033[00m" .format(prt))
def prBlack(prt): print("\033[98m {}\033[00m" .format(prt))

prGreen("Hello world")

这是一个诅咒的例子:

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)
