Well, on Windows you have to look for the Py2Exe package
(www.py2exe.org)
On Mac OS X you can use Py2App
(http://undefined.org/python/py2app.html)

Mind you, on Windows there is one big potentional problem: Python is
compiled with Visual Studio 2003 and needs msvcr71.dll.  So Py2Exe
wants to distribute that dll also, but if you don't have a valid Visual
Studio license, you are not allowed to.
It is explained further in this thread:
http://groups.google.com/group/comp.lang.python/browse_frm/thread/bccb45b7dae7ddd5/dacec12e300a74d4#dacec12e300a74d4

I doubt Microsoft will unleash their lawyers on you, but it is a
problem.

can't figure out error: module has no attribute...

[Chris_147]

but it seems to depend on from where I start the Python shell.

so I've got a module selfservicelabels.py with some variables defined,
like this:
BtnSave = "link=label.save"
DeliveryAutomaat= "//[EMAIL PROTECTED]'deliveryMethod' and @value='AU']"
This module is in the Lib directory.

Now when I do
import selfservicelabels
selfservicelabels.BtnSave
   -> link=nmbs.label.save
selfservicelabels.DeliveryAutomaat
   -> AttributeError: 'module' object has no attribute
'DeliveryAutomaat'

to make it more strange: PyCrust and Idle recognise DeliveryAutomaat
perfectly.
Everything above is done with Python 2.4.3 on Windows XP SP2

So after some testing it seems to depend on from which partition I
start Python.
So open commandline and navigate to a dir on C: everything works
perfectly.
Close python shell en navigate to D: some variables in
selfservicelabels.py are not known.
What is going on here?  Is this a known error?

Thanks for the reply.

you are indeed right, they were included from different places.
from C:\Python24\Lib and D:\mydir

But the strange thing is:
anywhere on C: the file from C:\Python24\Lib was included.
in D:\mydir the one from that directory
BUT: anywhere else on D: apparantly the one from D:\mydir was included
?!
I would expect it would come from c:\Python24\Lib.

Now I changed the files and of course I cannot reproduce it anymore.
Oh well, now it works.
