Best workflow and practices for releasing a new python package version on github and pypi

Question

I was wondering what is the best procedure or practices for releasing a new python package version on pypi and github.

For example, is this the typical workflow a major python package would follow?

1. On master branch, increment version number
   1. Set version='1.5.0' in setup.py
   2. Set __version__ = '1.5.0' in package __init__.py
2. Update CHANGELOG.md with new version
3. Run tox locally to verify package
4. Push changes git push origin master
5. Create tag git tag v1.5.0 -m "Release v1.5.0"
6. Push tag git push origin v1.5.0
7. Wait for Travis CI build to finish.
8. Build package python setup.py sdist bdist_wheel
9. Verify created packages
   1. test-sdist/bin/pip install dist/<package>-1.5.0.tar.gz
   2. test-wheel/bin/pip install dist/<package>-1.5.0-py2.py3-none-any.whl
10. Upload to PyPI Staging
    1. twine upload -r testpypi dist/<package>-1.5.0*
    2. pip install --user --no-cache-dir --extra-index-url https://testpypi.python.org/pypi <package>
11. Upload to PyPI Production
    1. twine upload dist/<package>-1.5.0>*
    2. pip install <package>==1.5.0
