thanks for reply. i already tried bring a python31.dll with my application,but when i copy them to a computer without python installed,the initialization will fail,and i got a error message as:
Fatal Python error: Py_Initialize: can't initialize sys standard streams ImportError: No module named encodings.utf_8 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.
i think maybe i have to take more than just a dll with my distribution... and this is not so comfortable for a application which just want some python scripting ability...

I did something more or less like this recently, except I included the python.exe too. I think you could try the following: Put your executable and the python dll (python31.dll?) plus any .pyd you'll need in the same directory. Make a Python31.zip containing all necessary .py files (if you download the source, the whole .py library tree should be there - just zip it or as much of it you need).
When you initialize python from your application add the path of Python31.zip to sys.path (e.g. sys.path.append('c:\home\myname\mydistro\Python31.zip')).
- Should be easy enough, you only need the dll for the raw interpreter, I think.
- This is trickier; you'll probably have a hard time weeding out "dangerous functions"... several that might be considered so are included in the interpreter (e.g. basic IO or execfile). I don't know how you should do that.
Regarding redistributable runtime: I think the license allows you to redistribute an unmodified python31.dll.

so plz consider an application which:
Exported some packages from itself to python and have a UI like a script editor window that enable user type python script in and excute it.
Users can only use these packages supported by application it self to maintain the application,they are limited to use the dangerous default packages like io things provided by original python distribution.
i thought there may be a python.dll that i just need take it with my
application,but seems im wrong,there isnt ?such a file looks like a
python
redistribute runtime.and about the question 2,the computer without python
installed can not have a python path that i should copy my pyd into.
?so how should i do these?i totally have no idea. thanks for any help.

There are a certain number of modules that are needed before Python can run imports from ZIP files.
You might want to look at how py2exe works to get an idea of what is needed and for the time being, you're probably better off with Python 2.6, since the number of available and working tools is far greater than for 3.1.

The embedded interpreter is failing to find the standard Python libraries. You need to call Py_SetPythonHome() before calling Py_Initialize().
