Thanks, yes, that's a good suggestion. I suspect they'd get a SyntaxError
today, but as another currently active thread suggested, that probably
would be considered more confusing than useful.

If you're lazy, you could distribute the server package to everyone
and just make sure that if someone tries to import it on python 2 then
they get a useful error.

Yeah, splitting client and server packages is on my to-do list. Was
just hoping to keep Python2 users from shooting themselves in the foot
with a server subpackage which wouldn't work.

Re: [Distutils] How to eliminate on part of a package?

[Chris Barker]

frankly, I'd give up n find_packages -- it's not that magic, it's just a
convenience function so you don't need to hand-specify them.

But in this case, you're doing something weird, so I"d just be explicit.

Though what I'd probably really do is make the client and server completely
separate packages. After all, you say your users only want the client side
anyway.

and if the server depends on the client (which I"d hope it doesn't!) then
you can simply make it a dependency.

If by "top/server tree" you mean that there are more subpackages under 
top.server (not just a server.py file as your diagram shows), then you need to 
filter out all of those subpackages as well, e.g.:

packages = setuptools.find_packages()
if sys.version_info.major < 3:
packages = [
pkg for pkg in packages
if pkg != "top.server" and not pkg.startswith("top.server.")
]
