Question

I have a simple python script, which imports various other modules I’ve written (and so on). Due to my environment, my PYTHONPATH is quite long. I’m also using Python 2.4.

What I need to do is somehow package up my script and all the dependencies that aren’t part of the standard python, so that I can email a single file to another system where I want to execute it. I know the target version of python is the same, but it’s on linux where I’m on Windows. Otherwise I’d just use py2exe.

Ideally I’d like to send a .py file that somehow embeds all the required modules, but I’d settle for automatically building a zip I can just unzip, with the required modules all in a single directory.

I’ve had a look at various packaging solutions, but I can’t seem to find a suitable way of doing this. Have I missed something?

[edit] I appear to be quite unclear in what I’m after. I’m basically looking for something like py2exe that will produce a single file (or 2 files) from a given python script, automatically including all the imported modules.

For example, if I have the following two files:

[\foo\module.py]
def example():
    print "Hello"

[\bar\program.py]
import module
module.example()

And I run:

cd \bar
set PYTHONPATH=\foo
program.py

Then it will work. What I want is to be able to say:

magic program.py

and end up with a single file, or possibly a file and a zip, that I can then copy to linux and run. I don’t want to be installing my modules on the target linux system.

I’ve come up with a solution involving modulefinder, the compiler, and the zip function that works well. Unfortunately I can’t paste a working program here as it’s intermingled with other irrelevant code, but here are some snippets:

zipfile = ZipFile(os.path.join(dest_dir, zip_name), 'w', ZIP_DEFLATED)
sys.path.insert(0, '.')
finder = ModuleFinder()
finder.run_script(source_name)

for name, mod in finder.modules.iteritems():
    filename = mod.__file__
    if filename is None:
        continue
    if "python" in filename.lower():
        continue

    subprocess.call('"%s" -OO -m py_compile "%s"' % (python_exe, filename))

    zipfile.write(filename, dest_path)
