Python's method of outputting colored text on the Windows command line

This example shows how python can output colored text on the Windows command line. Share with you for your reference. Specific analysis is as follows:

By default python text messages in the console output is black and white, if we can turn into color text output, output the effect will be more perfect, also very cool, isn't it, here is a demo code, this code is used to output a color class encapsulates the color words, just call the class inside of related method, is very simple.

#!/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. - www.jb51.net'''

    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')
