We wrote a small wrapper to a twitter app and published this information to http://pypi.python.org. But setup.py just contained a single field for specifying email / name of the author. How do I specify multiple contributors / email list, to the following fields since we would like this package to be listed under our names, much similar to how it shows up in http://rubygems.org.
author='foo',
author_email='foo.bar@gmail.com',
As far as I know, setuptools doesn't support using a list of strings in order to specify multiple authors. Your best bet is to list the authors in a single string:
author='Foo Bar, Spam Eggs',
author_email='foobar@baz.com, spameggs@joe.org',
I'm not sure if PyPI validates the author_email field, so you may run into trouble with that one. In any case, I would recommend you limit these to a single author and mention all contributors in the documentation or description.
This has been registered as a bug, actually, but it seems like support for multiple authors was not implemented. Here is an alternative solution. Here is an idea for how to provide a contact email for a project with multiple authors.
I'm sort of just piggybacking off of @modocache's answer, in case you want some specifics.
Throughout this answer, I'll be refering to a python3.6 version of the FOO-PYTHON-ENV\Lib\distutils\dist.py file

Consider using flit to build the package, as this build system supports multiple authors and maintainers. Store this metadata in pyproject.toml as follows:
[build-system]
requires = ["flit_core >=3.2,<4"]
build-backend = "flit_core.buildapi"
[project]
...
authors = [
{name = "First1 Last1", email = "name1@foo.bar"},
{name = "First2 Last2", email = "name2@foo.bar"},
]
maintainers = [
{name = "First1 Last1", email = "name1@foo.bar"},
{name = "First2 Last2", email = "name2@foo.bar"},
]
