py2exe

Have your executable implement a command line switch that results in something like:
 
   if sys.argv[1] == "-e":
      execfile(sys.argv[2])
      sys.exit()

Then your subprocess call below would look like:

   subprocess.call([sys.executable, "-e", 'script.py'])

and off you go.

I'm not remembering the details (and I no longer have access to the
codebase where I did it, although I was doing it for multiprocessing, so
the docs for that might help), but you need to point sys.executable to
something else.

You may find something useful here:

Nice trick, perfect solution. Thanks a lot!

Thanks also Aahz for the link!

A py2exe'd app includes pythonxx.dll and other things needed by Python 
and whatever your app uses.

I never needed this but I think/guess (pretty sure:) that should just 
work, i.e. if you have a "mymodule.py" within e.g. your package and then 
your py2exe'd app imports this it will just work.

Have you tried it, are you getting any error?

You should add the directory that contains the module to sys.path,
then you can import it.

Thomas

Marko,

You have lots of options, with one already presented (augment sys.path and use import).  Here are a couple more that I've used:

Execute an argument containing source supplied on the commmand line:  mycode.exe -c 'print "hello" ; import math ; print math.sqrt(2)'

   gns = dictionary of global symbols I want to expose, e.g., globals()

   code = compile(args.command+'\n', "command line", "exec")
   exec(code, gns)

Collect the name of the file that the users wants executed and simply execute it:

   filename = "usercode.py"
   execfile(filename, gns)

The first example is very general, get some source in a string, compile it and execute it.  The second is really just shorthand for doing exactly that.

HTH,
Eric

Subject: [Py2exe-users] Execute non-compiled code from a py2exe executable

Hello,
Is there a way to make a py2exe compiled code execute a non-compiled python code (without installing python)?

The idea is let part of the code non-compiled to allow the users to easily make some changes. They have windows non-admin access to their machine so in principle they can't install python.
Thanks for any hint! Cheers,
Marko

It works!

> Have you tried it, are you getting any error?

Actually I hadn't, sorry, I hadn't figured out it could be so easy...
All I needed to do was to append sys.path as Thomas said.

Now I understand better what py2exe does.

This is wonderful news for me, thanks a lot Werner and Thomas for the help!
