有个complier模块.

>>> import compiler
>>> help(compiler)
Help on package compiler:

NAME
compiler - Package for parsing and compiling Python source code

FILE
c:\python24\lib\compiler\__init__.py

DESCRIPTION
There are several functions defined at the top level that are imported
from modules contained in the package.

parse(buf, mode="exec") -> AST
Converts a string containing Python source code to an abstract
syntax tree (AST). The AST is defined in compiler.ast.

parseFile(path) -> AST
The same as parse(open(path))

walk(ast, visitor, verbose=None)
Does a pre-order walk over the ast using the visitor instance.
See compiler.visitor for details.

compile(source, filename, mode, flags=None, dont_inherit=None)
Returns a code object. A replacement for the builtin compile() function.

compileFile(filename)
Generates a .pyc file by compiling filename.

其实手工写一个更简单。
a.py 是要被编译的
a2.py是一个工具。

a.py的内容
class testa:
    pass

a2.py的内容
import a

这样，运行一下a2.py，那么a.py就被编译成a.pyc了。

哈哈,老马的这个方法很简便
不过有个疑惑,好像import会运行文件中的代码
如果脚本里面直接实现一些操作性的代码
比如复制/删除文件的而且没有if __name__ == '__main__'测试
那么可能会超出原始的期望,效率还很低
当然了,没有几个人会这么做

所以还是用complier吧又不麻烦

可以生成pyo文件。
但是需要写一个批处理或者在命令行输入：

python -O a1.py

那个是大写的英文字母O，不是0，呵呵。
这样就会出来一个a.pyo了。

又仔细看了一下，发现pyc和pyo文件是一样大的，遂拿出来winhex做了一番比较，把能找到的pyc和pyo都作了一下比较，发现内容都是一样的。
也就是说，生成的pyc改个扩展名为pyo就行了。
不过据说pyo是pyc的优化版本，但是目前还没看出来有啥区别，估计是我看得文件太少了？谁研究的比较深入能分享一下经验？

字节码可能是一样的，也许是去掉了象docstring之类的东西吧，不是很清楚。

 python -O a1.py怎么没法编译啊，倒是把脚本直接运行了。我用的compile倒是可以。

看我之前的邮件。
a1.py只有一个import语句，是用来编译a.py的。运行的话可以出来a.pyo，而被运行的a1.py没有任何变化的。

可能吧，不过目前倒是没有看出来有何不同。
字节数一样，内容一样。搜索了半天也没发现有人说明白这个问题的。

是象limodou说的那样，文档里面有说明。
