一、简介
py2exe是一个将python脚本转换成windows上的可独立执行的可执行程序(*.exe)的工具，这样，你就可以不用装python而在windows系统上运行这个可执行程序。
py2exe已经被用于创建wxPython,Tkinter,Pmw,PyGTK,pygame,win32com client和server,和其它的独立程序。py2exe是发布在开源许可证下的。
二、安装py2exe
从http://prdownloads.sourceforge.net/py2exe 下载并运行与你所安装的Python对应的py2exe版本的installer，这将安装py2exe和相应的例子；这些例子被安装在lib\site-packages\py2exe\samples目录下。
三、py2exe的用法
如果你有一个名为helloworld.py的python脚本，你想把它转换为运行在windows上的可执行程 序，并运行在没有安装python的 windows系统上，那么首先你应写一个用于发布程序的设置脚本例如mysetup.py，在其中的setup函数前插入语句 import py2exe 。
mysetup.py示例如下:
from distutils.core import setup import py2exe setup(console=["helloworld.py"])
如果显示错误提示的话 “ msvcp90.dll: no such file or directory”
请尝试下面的方法：
from distutils.core import setup import py2exe setup( console=["helloworld.py"], options = { "py2exe": { "dll_excludes": ["MSVCP90.dll"] } } )
然后按下面的方法运行mysetup.py: （dos: cmd => cd desktop => mysetup.py py2exe）
python mysetup.py py2exe
上面的命令执行后将产生一个名为dist的子目录，其中包含了helloworld.exe,python24.dll,library.zip这些文件。
如果你的helloworld.py脚本中用了已编译的C扩展模块，那么这些模块也会被拷贝在个子目录中，同样，所有的dll文件在运行时都是需要的，除了系统的dll文件。
dist子目录中的文件包含了你的程序所必须的东西，你应将这个子目录中的所有内容一起发布。
默认情况下，py2exe在目录dist下创建以下这些必须的文件：
1、一个或多个exe文件。
2、python##.dll。
3、几个.pyd文件，它们是已编译的扩展名，它们是exe文件所需要的；加上其它的.dll文件，这些.dll是.pyd所需要的。
4、一个library.zip文件，它包含了已编译的纯的python模块如.pyc或.pyo
上面的mysetup.py创建了一个控制台的helloword.exe程序，如果你要创建一个图形用户界的程序，那么你只需要将mysetup.py中的console=["helloworld.py"]替换为windows=["myscript.py"]既可。
py2exe一次能够创建多个exe文件，你需要将这些脚本文件的列表传递给console或windows的关键字参数。如果你有几个相关联的脚本，那么这是很有用的。
运行下面个命令，将显示py2exe命令的所有命令行标记。
python mysetup.py py2exe --help
Global options: --verbose (-v) run verbosely (default) --quiet (-q) run quietly (turns verbosity off) --dry-run (-n) don't actually do anything --help (-h) show detailed help message Options for 'py2exe' command: --optimize (-O) optimization level: -O1 for "python -O", -O2 for "python -OO", and -O0 to disable [default: -O0] --dist-dir (-d) directory to put final built distributions in (default is dist) --excludes (-e) comma-separated list of modules to exclude --dll-excludes comma-separated list of DLLs to exclude --ignores comma-separated list of modules to ignore if they are not found --includes (-i) comma-separated list of modules to include --packages (-p) comma-separated list of packages to include --compressed (-c) create a compressed zipfile --xref (-x) create and show a module cross reference --bundle-files (-b) bundle dlls in the zipfile or the exe. Valid levels are 1, 2, or 3 (default) --skip-archive do not place Python bytecode files in an archive, put them directly in the file system --ascii (-a) do not automatically include encodings and codecs --custom-boot-script Python file that will be run when setting up the runtime environment usage: setup_py2exe.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup_py2exe.py --help [cmd1 cmd2 ...] or: setup_py2exe.py --help-commands or: setup_py2exe.py cmd --help
四、指定额外的文件
一些应用程序在运行时需要额外的文件，诸如配置文件、字体、位图。
如果在安装脚本中用data_files可选项指定了那些额外的文件，那么py2exe能将这些文件拷贝到dist子目录中。data_files应包含一个元组(target-dir, files)列表，其中的files是这些额外的文件的列表。
示例如下：
PythonCode: # mysetup.py
from distutils.core import setup import glob import py2exe setup(console=["helloworld.py"], data_files=[("bitmaps", ["bm/large.gif", "bm/small.gif"]), ("fonts", glob.glob("fonts\\*.fnt"))], )
说明：data_files选项将创建一个子目录dist\bitmaps，其中包含两个.gif文件；一个子目录dist\fonts，其中包含了所有的.fnt文件。
五、Windows NT services
你可以通过传递一个service关键字参数给setup函数来建造Windows NT services
,这个service参数的值必须是一个Python模块名(包含一service类)的列表。
示例如下：
PythonCode: # mysetup.py
from distutils.core import setup import py2exe setup(service=["MyService"])
所建造的可执行的service是可以通过在其后跟一定的命令行参数标记来自行安装和卸载的。你可以通过在这个可执行的service(exe)后跟一-help参数来得到更多的帮助。
六、COM servers
你可以通过传递一个com_server 关键字参数给setup函数来建造Windows NT services
,这个service参数的值必须是一个Python模块名(包含一个或多个COM server 类)的列表。
示例如下：
PythonCode: # mysetup.py
from distutils.core import setup import py2exe setup(com_server=["win32com.server.interp"])
默认情况下，DLL和EXE servers被建造，你不需要它们的话你可以简单的删除它们。
一个标准的py2exe setup文件编写
-*- coding: cp936 -*- from distutils.core import setup import py2exe includes = ["encodings", "encodings.*"] #要包含的其它库文件 options = {"py2exe": {"compressed": 1, #压缩 "optimize": 2, "ascii": 1, "includes":includes, "bundle_files": 1 #所有文件打包成一个exe文件 } } setup( options = options, zipfile=None, #不生成library.zip文件 console=[{"script": "hello.py", "icon_resources": [(1, "hello.ico")] }]#源文件，程序图标 )
新 版本已经可以打包为一个文件了，以前都是一堆dll,pyd的。具体的变化其实只有一个地方。就是options里增加bundle_files项，值为 1表示pyd和dll文件会被打包到exe文件中，且不能从文件系统中加载python模块；值为2表示pyd和dll文件会被打包到exe文件中，但是 可以从文件系统中加载python模块。另外setup中使用zipfile=None可以不生成library.zip。
例如原来 的：
from distutils.core import setup import py2exe includes = ["encodings", "encodings.*"] options = {"py2exe": { "compressed": 1, "optimize": 2, "includes": includes, } } setup( version = "0.1.0", description = "search panda", name = "search panda", options = options, windows=[{"script": "search.py", "icon_resources": [(1, "search.ico")] }], )
只需要改为：
from distutils.core import setup import py2exe includes = ["encodings", "encodings.*"] options = {"py2exe": { "compressed": 1, "optimize": 2, "includes": includes, "bundle_files": 1 } } setup( version = "0.1.0", description = "search panda", name = "search panda", options = options, zipfile=None, windows=[{"script": "search.py", "icon_resources": [(1, "search.ico")] }], )
比如，这里我打包以前的DelphiCode2HTML的
# -*- coding: gbk -*- from distutils.core import setup import py2exe includes = ["encodings", "encodings.*"] options = {"py2exe": {"compressed": 1, "optimize": 2, "ascii": 1, "includes":includes, "bundle_files": 1} } setup( options = options, zipfile=None, name = "HelloGuys.", description = "this is a py2exe test", windows=[{"script": "F:\我的程序\Python\CSDN Code Edit\Code2Html.py", "icon_resources": [(1, "F:\书籍\我的图标\图标xp\Convert.ico")] }] )

注意 windows 的用法，他可以代替 console， 如果你要集成 wxpython 的时候，一定会用的 ！
更多请查看 http://www.py2exe.org/index.cgi/ListOfOptions
如果程序中含有email类，并且压缩时出现类似 “ImportError: No module named multipart ” 的错误，你需要如下的设置：
1. 尝试将Lib下的email包，复制到当前文件夹中
2. 把['emai'] 放入includes中
3. 把['email']放入packages中
4. 继续运行py2exe
如：
from distutils.core import setup import py2exe includes = ["encodings", "encodings.*",'email'] options = {"py2exe": { "compressed": 1, "optimize": 2, "includes": includes, "bundle_files": 1, "packages": ['email'], "dll_excludes": ["MSVCP90.dll"] } } setup( version = "0.1.0", description = "3th", name = "For My Lover", options = options, zipfile=None, windows=[{"script": "love.py", "icon_resources": [(1, "roses.ico")] }], )
