python在windows命令行下输出彩色文字代码详解编程语言

默认情况下python在控制台输出的文字信息都是黑白的，如果能将文字做成彩色的输出，输出效果会更完美，也很酷，不是吗，下面是一段演示代码，这段代码封装了一个color类用来输出带颜色的文字，只要调用该类里面的相关方法就可以了，非常简单。

#!/usr/bin/env python  
#encoding: utf-8

STD_INPUT_HANDLE = -10 
STD_OUTPUT_HANDLE= -11 
STD_ERROR_HANDLE = -12 
  
FOREGROUND_BLACK = 0x0 
FOREGROUND_BLUE = 0x01 # text color contains blue. 
FOREGROUND_GREEN= 0x02 # text color contains green. 
FOREGROUND_RED = 0x04 # text color contains red. 
FOREGROUND_INTENSITY = 0x08 # text color is intensified. 
  
BACKGROUND_BLUE = 0x10 # background color contains blue. 
BACKGROUND_GREEN= 0x20 # background color contains green. 
BACKGROUND_RED = 0x40 # background color contains red. 
BACKGROUND_INTENSITY = 0x80 # background color is intensified.
