怎么改python的输出颜色

用Python写命令行程序的时候，单一的输出颜色太单调。其实我们可以加些色彩，比如用红色表示警告，绿色表示结果正常等。网上也有几篇类似的帖子，但是没有把问题讲清楚，贴的代码也不是太清晰。这里，对Windows下CMD输出彩色进行完整的讲解和易用的代码函数库展示。

原理解析参见：

核心代码介绍

std_out_handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)

def set_cmd_text_color(color, handle=std_out_handle):

Bool = ctypes.windll.kernel32.SetConsoleTextAttribute(handle, color)

return Bool

set_cmd_text_color(这里参数要填颜色的16进制编码)

颜色的讲解：

这个函数支持2位十六进制编码，比如0x12,0x03,0xef。取值都是0~f。区别在于，前一位指的是背景色，后一位指的是前景色，我们为了方便，可以给这些颜色编码定义一些有意义的别名。比如：

# Windows CMD命令行 字体颜色定义 text colors

FOREGROUND_BLACK = 0x00 # black.

FOREGROUND_DARKBLUE = 0x01 # dark blue.

FOREGROUND_DARKGREEN = 0x02 # dark green.

FOREGROUND_DARKSKYBLUE = 0x03 # dark skyblue.

FOREGROUND_DARKRED = 0x04 # dark red.

FOREGROUND_DARKPINK = 0x05 # dark pink.

FOREGROUND_DARKYELLOW = 0x06 # dark yellow.

FOREGROUND_DARKWHITE = 0x07 # dark white.

FOREGROUND_DARKGRAY = 0x08 # dark gray.

FOREGROUND_BLUE = 0x09 # blue.

FOREGROUND_GREEN = 0x0a # green.

FOREGROUND_SKYBLUE = 0x0b # skyblue.

FOREGROUND_RED = 0x0c # red.

FOREGROUND_PINK = 0x0d # pink.

FOREGROUND_YELLOW = 0x0e # yellow.

FOREGROUND_WHITE = 0x0f # white.

# Windows CMD命令行 背景颜色定义 background colors

BACKGROUND_BLUE = 0x10 # dark blue.

BACKGROUND_GREEN = 0x20 # dark green.

BACKGROUND_DARKSKYBLUE = 0x30 # dark skyblue.

BACKGROUND_DARKRED = 0x40 # dark red.

BACKGROUND_DARKPINK = 0x50 # dark pink.

BACKGROUND_DARKYELLOW = 0x60 # dark yellow.

BACKGROUND_DARKWHITE = 0x70 # dark white.

BACKGROUND_DARKGRAY = 0x80 # dark gray.

BACKGROUND_BLUE = 0x90 # blue.

BACKGROUND_GREEN = 0xa0 # green.

BACKGROUND_SKYBLUE = 0xb0 # skyblue.

BACKGROUND_RED = 0xc0 # red.

BACKGROUND_PINK = 0xd0 # pink.

BACKGROUND_YELLOW = 0xe0 # yellow.

BACKGROUND_WHITE = 0xf0 # white.

注意下边这句：把不同颜色进行或操作，结果肯定还是16种颜色的一种。

set_cmd_text_color(FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE)

完整代码

我把每种颜色代码都封装成了易用的函数，可以根据需要在自己的程序里直接导入相应函数进行彩色输出。

比如原来是 print 'hello' 现在直接 printBlue('hello') 就可以了。

#! /usr/bin/env python

#coding=utf-8

import ctypes,sys

STD_INPUT_HANDLE = -10

STD_OUTPUT_HANDLE = -11

STD_ERROR_HANDLE = -12

# 字体颜色定义 ,关键在于颜色编码，由2位十六进制组成，分别取0~f，前一位指的是背景色，后一位指的是字体色

#由于该函数的限制，应该是只有这16种，可以前景色与背景色组合。也可以几种颜色通过或运算组合，组合后还是在这16种颜色中

# Windows CMD命令行 字体颜色定义 text colors

FOREGROUND_BLACK = 0x00 # black.

FOREGROUND_DARKBLUE = 0x01 # dark blue.

FOREGROUND_DARKGREEN = 0x02 # dark green.

FOREGROUND_DARKSKYBLUE = 0x03 # dark skyblue.

FOREGROUND_DARKRED = 0x04 # dark red.

FOREGROUND_DARKPINK = 0x05 # dark pink.

FOREGROUND_DARKYELLOW = 0x06 # dark yellow.

FOREGROUND_DARKWHITE = 0x07 # dark white.

FOREGROUND_DARKGRAY = 0x08 # dark gray.

FOREGROUND_BLUE = 0x09 # blue.

FOREGROUND_GREEN = 0x0a # green.

FOREGROUND_SKYBLUE = 0x0b # skyblue.

FOREGROUND_RED = 0x0c # red.

FOREGROUND_PINK = 0x0d # pink.

FOREGROUND_YELLOW = 0x0e # yellow.

FOREGROUND_WHITE = 0x0f # white.

# Windows CMD命令行 背景颜色定义 background colors
