Python脚本如果需要发布给Windows客户运行，可以使用py2exe来编译成exe可执行文件, 这样用户就不用安装Python运行环境。 顺便还保护了源代码。（不过要注意，还是可以反编译的）
下载及安装
首先要确认本地安装的python的版本，然后选择Py2exe版本。
到目前为止似乎还不支持Python3的脚本。 还好我一般不用Python3，因为多数Linux系统自带的都是2.7版本的。
使用方法
例如需要编译的脚本为：hello.py
'''

@author: tudaxia
'''
#!/usr/bin/env python
# coding:utf-8
def HelloWorld():
print "Hello World!"
if __name__=="__main__":
HelloWorld()
编写一个编译脚本，例如hello_setup.py

#!/usr/bin/env python
# coding:utf-8
from distutils.core import setup
import py2exe
includes = ["encodings", "encodings.*"]
options = {"py2exe":
{"compressed": 1,
"optimize": 2,
"ascii": 1,
"includes":includes,
"bundle_files": 1 # 表示将所有的模块打包成一个exe文件
}}
setup(
options=options,
zipfile=None,
console=[{"script": "hello.py", "icon_resources": [(1, "tudaxia.ico")]}], #可以配置自己的图标
version = "2012.09.20", # 按实际情况
description = "Hello World!", # 按实际情况
name = "hello", # 按实际情况
)
在命令行下，执行以下命令
d:\demo\hello_setup.py py2exe
在当前目录下会生成一个dist目录，里面有hello.exe可执行文件。
这样hello.exe文件就可以脱离python环境（其实是自带了一个）独立运行了。
编译options参数有很多，可以执行命令查看帮助：
D:\demo>hello_setup.py py2exe --help
Common commands: (see '--help-commands' for more)
setup.py build will build the package underneath 'build/'
setup.py install will install the package
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
--no-user-cfg ignore pydistutils.cfg in your home directory
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: hello_setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: hello_setup.py --help [cmd1 cmd2 ...]
or: hello_setup.py --help-commands
or: hello_setup.py cmd --help
