们经常要用py2exe将python脚本转换为可执行文件，但是有一个麻烦就是要针对脚本写一个setup.py，在setup.py中指定一些信息，然后运行setup.py XX.py来生成执行文件。为避免每次都要写setup.py，以下提供一个脚本工具pyfly.py,只要运行pyfly.py
yourfile.py就能生成yourfile.exe。还可以为其指定其他参数，比如-i myicon.ico为生成的可执行文件添加图标；-p
console指定生成控制台程序，-p windows指定生成windows程序；-c yes指定用upx压缩可执行文件以减小大小，-c no执行不压缩可执行文件；-d out_directory 指定生成的可执行文件的输出目录。（-c yes 选项需要将upx.exe放置在系统的环境变量PATH所包含的目录中，或者将upx.exe的路径加入PATH中)
运行"pyfly.py pyfly.py", 就立即在当前目录下生成pyfly.exe,将pyfly.exe置于环境变量PATH中能找到的位置，然后在任意目录中就可为你的python脚本生成单文件的可执行程序了。
要想运行该段代码，你需要准备以下两件事，下载WConio，该模块主要是用来控制windows控制台彩色文字输出的，下载地址为：-

，记住下载exe的版本，Python2.5版本的下载地址为：http://newcenturycomputers.net/projects/download.cgi/WConio-1.5.win32-py2.5.exe用Winrar打开该exe，将里面的WConio.py和_WConio.pyd直接复制到D:/Python25/Lib/site-packages目录下就可以了。下面是WConio官方的例子

import WConio
#Store current attribute settings
old_setting = WConio.gettextinfo()[4] & 0x00FF
#Clear the screen
WConio.clrscr()
#Display something in low video
WConio.lowvideo()
WConio.cputs("Low video/r/n")
#Display something in high video
WConio.highvideo()
WConio.cputs("High video/r/n")
#Display something in normal video
WConio.normvideo()
WConio.cputs("Normal video/r/n")
#Display some text in color
WConio.textattr(WConio.LIGHTRED)
WConio.cputs("Light Red text/r/n")
#Display some more text in color
WConio.textattr(WConio.LIGHTBLUE)
WConio.cputs("Light BLUE text/r/n")
#leave a blank line - this shows you that print still works
#Set heading colour but using print
WConio.textattr(WConio.LIGHTGREEN)
print("Times table/r/n")
#Back to normal intensity for white
WConio.normvideo()
for i in range(12) :
WConio.textattr(WConio.WHITE)
a = "%2d * 2 = " % (i)
WConio.cputs(a)
WConio.textattr(WConio.YELLOW)
a = "%2d/r/n" % (i*2)
WConio.cputs(a)
WConio.textattr(WConio.CYAN)
WConio.cputs("/n/nPress any key to end/r/n")
#Wait for a key to be pressed
WConio.getch()
#Retore old attribute settings
WConio.textattr(old_setting)
接下来下载upx，http://upx.sourceforge.net/
下面是pyfly.py的源代码
