====== Python py2exe 创建可执行文件 ======


===== py2exe是什么？ =====

py2exe是一种python发布工具，可以把python脚本转换成windows下的可执行程序，不需要安装python便可运行。
py2exe现在可以用来创建使用了wxPython, Tkinter, Pmw, PyGTK, pygame, win32com client and server 等模块的程序。

详细介绍可以看它的官方网站 http://www.py2exe.org/


===== 下载安装py2exe =====

py2exe目前的版本是0.5.4，根据你安装的python的版本选择下载的文件 

[[http://sourceforge.net/project/showfiles.php?group_id=15583&package_id=35995&release_id=474800　]]

安装后的文件应该在你的python安装目录下的Lib\site-packages\py2exe


===== 使用py2exe =====

我们先准备一个简单的python程序hello.py
<code python>
# hello.py
def main():
    print "Hello, World!"
if __name__ == '__main__':
   main() 
</code>

然后为使用py2exe写一个脚本setup.py

<code python>
# setup.py
from distutils.core import setup
import py2exe      

setup(console=["hello.py"])
</code>

运行setup.py，记得要传一个参数给它

python setup.py py2exe

应该看到一些输出信息

py2exe会在当前目录下生成两个目录 build和dist

build里是一些py2exe运行时产生的中间文件，dist里有最终的可执行文件
<file>
 library.zip
 w9xpopen.exe
 python23.dll
 hello.exe
</file>

现在可以运行hello.exe了

<file>
E:\Projects\WorkSpace\Python\dist>hello

Hello, World!
</file>


不过记得如果要发布到别的机器上时，library.zip、 w9xpopen.exe、python23.dll这几个文件是必须要和hello.exe在一起的。


最后，大家试试运行

python setup.py py2exe --help
