Python在两种系统下输出彩字的实例解析

前言

最近在项目中需要输出彩色的文字来提醒用户，以前写过，但是只能在win上面运行。

今天搜了下看有没有在win和Linux上通用的输出彩色文字的模块，结果发现没有，，于是就自己弄了一个，分享下，以后用的时候翻翻博客，方便别人也方便自己。

win下输出彩色文字，网上有两种方法一种是用system执行命令来设置颜色，感觉还是不太好，用ctypes模块实现更好点。

linux下设置颜色，网上只找到了一种方法，下面不废话了，直接贴下代码：

示例代码

import platform
if &＃39;Windows&＃39; in platform.system():
 import sys
 import ctypes
 stdInputHandle = -10
 stdOutputHandle = -11
 stdErrorHandle = -12
 foreGroundBLUE = 0x09
 foreGroundGREEN = 0x0a
 foreGroundRED = 0x0c
 foreGroundYELLOW = 0x0e
 stdOutHandle=ctypes.windll.kernel32.GetStdHandle(stdOutputHandle)
 def setCmdColor(color,handle=stdOutHandle):
 return ctypes.windll.kernel32.SetConsoleTextAttribute(handle, color)
 def resetCmdColor():
 setCmdColor(foreGroundRED | foreGroundGREEN | foreGroundBLUE)
 def printBlue(msg):
 setCmdColor(foreGroundBLUE)
 sys.stdout.write(msg + &＃39;\n&＃39;)
 resetCmdColor()
 def printGreen(msg):
 setCmdColor(foreGroundGREEN)
 sys.stdout.write(msg + &＃39;\n&＃39;)
 resetCmdColor()
 def printRed(msg):
 setCmdColor(foreGroundRED)
 sys.stdout.write(msg + &＃39;\n&＃39;)
 resetCmdColor()
 def printYellow(msg):
 setCmdColor(foreGroundYELLOW)
 sys.stdout.write(msg + &＃39;\n&＃39;)
 resetCmdColor()
else:
 STYLE = {
 &＃39;fore&＃39;:{
 &＃39;red&＃39;: 31,
 &＃39;green&＃39;: 32,
 &＃39;yellow&＃39;: 33,
 &＃39;blue&＃39;: 34,
 }
 }
 def UseStyle(msg, mode = &＃39;&＃39;, fore = &＃39;&＃39;, back = &＃39;40&＃39;):
 fore = &＃39;%s&＃39; % STYLE[&＃39;fore&＃39;][fore] if STYLE[&＃39;fore&＃39;].has_key(fore) else &＃39;&＃39;
 style = &＃39;;&＃39;.join([s for s in [mode, fore, back] if s])
 style = &＃39;\033[%sm&＃39; % style if style else &＃39;&＃39;
 end = &＃39;\033[%sm&＃39; % 0 if style else &＃39;&＃39;
 return &＃39;%s%s%s&＃39; % (style, msg, end)
 def printRed(msg):
 print UseStyle(msg,fore=&＃39;red&＃39;)
 def printGreen(msg):
 print UseStyle(msg,fore=&＃39;green&＃39;)
 def printYellow(msg):
 print UseStyle(msg,fore=&＃39;yellow&＃39;)
 def printBlue(msg):
 print UseStyle(msg,fore=&＃39;blue&＃39;)

效果图：

Windows：

C:\luan\lu4n.com-sqli>python
Python 2.7 (r27:82525, Jul 4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)] on win

>>> from color import *
>>> printRed(&＃39;Red&＃39;)
Red
>>> printGreen(&＃39;Green&＃39;)
Green
>>> printYellow(&＃39;Yellow&＃39;)
Yellow
>>> printBlue(&＃39;Blue&＃39;)
Blue
>>> print &＃39;http://lu4n.com/&＃39;
http://lu4n.com/
>>>

Linux:

[root@Luan ~]# nano test_color.py
[root@Luan ~]# python
Python 2.7.5 (default, Jun 17 2014, 18:11:42) 
[GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux2

>>> from test_color import *
>>> printRed(&＃39;Red&＃39;)
Red
>>> printGreen(&＃39;Green&＃39;)
Green
>>>

用起来很容易，直接from color import *就可以用了，有4种常用颜色可以使用，分别写了4个函数：

提示信息 printBlue

成功信息 printGreen

失败信息 printRed

警告信息 printYellow

和bootstrap的几种颜色差不多，应该够用了。
