python在windows命令行下输出彩色文字的方法_python

分享到:

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. - 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')

希望本文所述对大家的Python程序设计有所帮助。
