FWIW, I would vote for the "__version__", "__author__", etc assignments being after the imports. Reason being cases where the "__version__" is not from VCS, but is calculated from pkg_resources:

from pkg_resources import get_distribution
__version__ = get_distribution('mypackage').version

Also, then more useful things like "__all__" (which can very reasonably rely on imports), can be together with "__version__" and "__author__" assignments.

I would vote:

dunder assignments
other code...

</2 cents>

In that case would you be open to a patch to update the PEP accordingly?

Additionally, does that official statement cover other dunder assignments (e.g. "__author__"?). If so I'll update the PEP8 tool accordingly.

FWIW, I think __version__, __author__ etc. were bad ideas. Almost nobody manages these correctly. Note that the PEP 8 section starts with less than an endorsement: "If you have to have Subversion, CVS, or RCS crud in your source file, do it as follows."

That said, if an official answer is required, common sense would suggest that __version__ should go before the imports. (I would put it before the docstring too, except then the docstring wouldn't be a docstring any more. Go figure.)

I don't know an official answer. The convention I've observed is
overwhelmingly in one direction: import statements come before any
assignment statements.
