在终端上打印颜色？

Python版本： 3.6.7（32位）

根据@ joeld的回答,愚蠢的简单

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

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

我已经将@joeld的答案包装到一个具有全局函数的模块中,我可以在代码中的任何地方使用它.

file: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

用法如下:

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

对于Windows,除非使用win32api,否则无法使用颜色打印到控制台.

对于Linux来说,它就像使用print一样简单,其中包含了转义序列:

颜色

对于像盒子一样打印的字符,它实际上取决于您用于控制台窗口的字体.英镑符号效果很好,但它取决于字体:

#

我最终做到了这一点,我觉得它最干净:

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)

建立在@joeld的答案上,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

对color_print新格式化程序的一些更新,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:italic,fast blinking并且strikethrough可能无法在所有终端上运行,不适用于Mac/Ubuntu.

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

你可以使用CLINT:

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

从GitHub获取它.

注意with关键字与需要重置的修饰符(使用Python 3和Colorama)的混合程度如何:

from colorama import Fore, Style
import sys

class Highlight:
  def __init__(self, clazz, color):
    self.color = color
    self.clazz = clazz
  def __enter__(self):
    print(self.color, end="")
  def __exit__(self, type, value, traceback):
    if self.clazz == Fore:
      print(Fore.RESET, end="")
    else:
      assert self.clazz == Style
      print(Style.RESET_ALL, end="")
    sys.stdout.flush()

with Highlight(Fore, Fore.GREEN):
  print("this is highlighted")
print("this is not")

您可以使用curses库的Python实现:http: //docs.python.org/library/curses.html

此外,运行此,你会找到你的盒子:

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

# Pure Python 3.x demo, 256 colors
# Works with bash under Linux and MacOS

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)

# Simple usage: print(fg("text", 160))

如果您正在编写游戏,或许您想要更改背景颜色并仅使用空格？例如:

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

如果你使用的是Windows,那么就去吧!

# 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 ... ")

"""
.. versionadded:: 0.9.2

Functions for wrapping strings in ANSI color codes.

Each function within this module returns the input string ``text``, wrapped
with ANSI color codes for the appropriate color.

For example, to print some text as green on supporting terminals::

    from fabric.colors import green

    print(green("This text is green!"))

Because these functions simply return modified strings, you can nest them::

    from fabric.colors import red, green

    print(red("This sentence is red, except for " + \
          green("these words, which are green") + "."))

If ``bold`` is set to ``True``, the ANSI flag for bolding will be flipped on
for that particular invocation, which usually shows up as a bold or brighter
version of the original color on most terminals.
"""


def _wrap_with(code):

    def inner(text, bold=False):
        c = code
        if bold:
            c = "1;%s" % c
        return "\033[%sm%s\033[0m" % (c, text)
    return inner

red = _wrap_with('31')
green = _wrap_with('32')
yellow = _wrap_with('33')
blue = _wrap_with('34')
magenta = _wrap_with('35')
cyan = _wrap_with('36')
white = _wrap_with('37')

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

Asciicast:

一个更简单的选择是使用包中的cprint功能termcolor.

它还支持%s, %d打印格式

这是一个curses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)

好极了!另一个版本

虽然我觉得这个答案很有用,但我修改了一下.这个Github Gist就是结果

用法

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

此外,你可以包装常见的用法:

print colors.error('sorry, ')

https://gist.github.com/Jossef/0ee20314577925b4027f

另一个包装python 3打印功能的pypi模块:

https://pypi.python.org/pypi/colorprint

如果你也可以在python 2.x中使用它from __future__ import print.这是模块pypi页面中的python 2示例:

from __future__ import print_function
from colorprint import *

print('Hello', 'world', color='blue', end='', sep=', ')
print('!', color='red', format=['bold', 'blink'])

输出"Hello,world!" 用蓝色的字和感叹号大胆的红色和闪烁.

如果你使用Django

>>> from django.utils.termcolors import colorize
>>> print colorize("Hello World!", fg="blue", bg='red',
...                 opts=('bold', 'blink', 'underscore',))
Hello World!
>>> help(colorize)

快照:

(我通常在runserver终端上使用彩色输出进行调试,所以我添加了它.)

_{您可以测试它是否已安装在您的计算机中:
$ python -c "import django; print django.VERSION"
要安装它,请检查:如何安装Django}

试试看!!
