python在windows命令行下输出彩色文字的方法

本文实例讲述了python在windows命令行下输出彩色文字的方法。分享给大家供大家参考。具体分析如下：

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

import ctypes

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.

class Color:

    ''' See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winprog/winprog/windows_api_reference.asp

    for information on Windows APIs. - 3water.com'''

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

    def set_cmd_color(self, color, handle=std_out_handle):

        """(color) -> bit

        Example: set_cmd_color(FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE | FOREGROUND_INTENSITY)

        """

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

        return bool

    def reset_color(self):

        self.set_cmd_color(FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE)

    def print_red_text(self, print_text):

        self.set_cmd_color(FOREGROUND_RED | FOREGROUND_INTENSITY)

        print print_text

        self.reset_color()

    def print_green_text(self, print_text):

        self.set_cmd_color(FOREGROUND_GREEN | FOREGROUND_INTENSITY)

        print print_text

        self.reset_color()

    def print_blue_text(self, print_text):

        self.set_cmd_color(FOREGROUND_BLUE | FOREGROUND_INTENSITY)

        print print_text

        self.reset_color()

    def print_red_text_with_blue_bg(self, print_text):

        self.set_cmd_color(FOREGROUND_RED | FOREGROUND_INTENSITY| BACKGROUND_BLUE | BACKGROUND_INTENSITY)

        print print_text

        self.reset_color()   

if __name__ == "__main__":

    clr = Color()

    clr.print_red_text('red')

    clr.print_green_text('green')

    clr.print_blue_text('blue')

    clr.print_red_text_with_blue_bg('background')

希望本文所述对大家的Python程序设计有所帮助。
