<p>At a high level, the steps to upload a package to PyPi are as follows:</p>
<ol>
<li>Write the project code</li>
<li>Create a release on GitHub and put it in the <code>download_url</code> of setup.py</li>
<li>Write a setup.py file to build and describe the project</li>
<li>Write a setup.cfg file pointing to the readme</li>
<li>create a source distribution</li>
</ol>
<h1 id="write-the-project-code">Write the project code</h1>
<p>I'm not going to cover how to build a python project in this post, but here's
the very small and simple project I used when learning this procedure:
<a href="https://github.com/kylep/jsc2f">GitHub: kylep/jsc2f</a>.</p>
<hr>
<h1 id="create-a-release-on-github">Create a Release on GitHub</h1>
<p>Log into your GitHub project and click on releases. If you can't find the link,
you can also just append <code>/releases</code> to the end of the URL to get there.</p>
<p>Click "Create a new release". Enter your tag and branch, along with a release
title and description.</p>
<p>Under the Assets section of the new release there's a (tar.gz) link to download
the source code. If you right click it and copy the URL, that's used next in
the setup.py file.</p>

<h1 id="write-a-setuppy-file">Write a setup.py file</h1>
<p>Here's mine. Check GitHub to see if I've changed it.
The <code>download_url</code> value comes from the GitHub release.</p>
<pre><code class="language-python">from setuptools import setup

# Without this you'll get no description on the pypi site
with open("README.md", "r") as fh:
    long_description = fh.read()

setup(
    name='jsc2f',
    packages=['jsc2f'], # Alternatively you can use find_packages()
    version='0.1', # match the github release you make later

<hr>
<h1 id="write-setupcfg">Write setup.cfg</h1>
<p>This goes in the project root next to setup.py.</p>
<p><code>vi setup.cfg</code></p>
<pre><code class="language-ini">[metadata]

<h1 id="creating-a-source-distribution">Creating a source distribution</h1>
<p>For this you use the python <a href="https://docs.python.org/2/distutils/sourcedist.html">sdist</a>
tool and <a href="https://pypi.org/project/twine/">twine</a>.</p>
<p>From the git project root:</p>
<pre><code class="language-bash">pip install twine

# This will create dist/
python setup.py sdist

# Twine uploads the dist/ files to Pypi
twine upload --skip-existing dist/*
# Enter your username and password for PyPI
</code></pre>
