 # Python Buildpack Changelog
 # 128
 Upgrade pip, pin to Pipenv v11.8.2.
 # 127
 Pin to Pipenv v11.7.1.
 # 126
 Bugfixes.
 # 125
 Bugfixes.
 # 124
 Update buildpack to automatically install `[dev-packages]` during Heroku CI Pipenv builds.
 - Skip installs if Pipfile.lock hasn't changed, and uninstall stale dependencies with Pipenv.
 - Set `PYTHONPATH` during collectstatic runs.
 - No longer warn if there is no `Procfile`.
 - Update Pipenv's "3.6" runtime specifier to point to "3.6.4".
 # 123
 Update gunicorn `init.d` script to allow overrides.
 # 122
 Update default Python to v3.6.4.
 # 121
 Update default Python to v3.6.3.
 # 120
 Use `$ pipenv --deploy`.
 # 119
 Improvements to Pipenv support, warning on unsupported Python versions.
 - We now warn when a user is not using latest 2.x or 3.x Python.
 - Heroku now supports `[requires]` `python_full_version` in addition to `python_version`.
 # 118
 Improvements to Pipenv support.
 # 117
 Bug fix.
 # 116
 Vendoring improvements.
 - Geos libraries should work on Heroku-16 now.
 - The libffi/libmemcached vendoring step is now skipped on Heroku-16 (since they are installed in the base image).
 # 115
 Revert a pull request.
 - No longer using `sub_env` for `pip install` step.
 # 114
 - Bugfixes.
 Blacklisting `PYTHONHOME` and `PYTHONPATH` for older apps. Upgrades to nltk support.
 # 113
 Updates to Pipenv support.
 # 112
 Bugfix.
 - Fixed grep output bug.
 # 111
 Linting, bugfixes.
 # 110
 Update default Python to 3.6.2.
 # 109
 Update Default Python to 3.6.1, bugfixes.
 - Fixed automatic pip uninstall of dependencies removed from requirements.txt.
 # 108
 Fix output for collectstatic step.
 # 107
 Bugfix for C dependency installation.
 # 106
 Don't install packages that could mess up packaging.
 - The Python buildpack will automatically remove `six`, `pyparsing`, `appdirs`,
   `setuptools`, and `distribute` from a `requirements.txt` file now, as these
   packages are provided by the Python buildpack.
 # 105
 Improvements to output messaging.
 # 104
 General improvements.
 - Fix for Heroku CI.
 - Use `pkg_resources` to check if a distribution is installed instead of
  parsing `requirements.txt`. ([#395][395])
 [395]: https://github.com/heroku/heroku-buildpack-python/pull/395
 ## 103
 Bug fixes and improvements.
 - Fix for Pipenv.
 - Fix for Heroku CI.
 - Improve handling of WEB_CONCURRENCY when using multiple buildpacks.
 - Adjust environment variables set during the build to more closely match those in the dyno environment (DYNO is now available, STACK is not).
 - Restore the build cache prior to running bin/pre_compile.
 ## 102
 Buildpack code cleanup.

 Recommended web frameworks include **Django** and **Flask**. The recommended webserver is **Gunicorn**. There are no restrictions around what software can be used (as long as it's pip-installable). Web processes must bind to `$PORT`, and only the HTTP protocol is permitted for incoming connections.
-Python packages with C dependencies that are not [available on the stack image](https://devcenter.heroku.com/articles/stack-packages) are generally not supported, unless `manylinux` wheels are provided by the package maintainers (common).

 # Python: Getting Started
 A barebones Django app, which can easily be deployed to Heroku.
 This application supports the [Getting Started with Python on Heroku](https://devcenter.heroku.com/articles/getting-started-with-python) article - check it out.
 ## Running Locally
 Make sure you have Python [installed properly](http://install.python-guide.org). Also, install the [Heroku CLI](https://devcenter.heroku.com/articles/heroku-cli) and [Postgres](https://devcenter.heroku.com/articles/heroku-postgresql#local-setup).
 ```sh
 $ git clone git@github.com:heroku/python-getting-started.git
 $ cd python-getting-started
 $ pipenv install
 $ createdb python_getting_started
 $ python manage.py migrate
 $ python manage.py collectstatic
 $ heroku local
 ```
 Your app should now be running on [localhost:5000](http://localhost:5000/).
 ## Deploying to Heroku
 ```sh
 $ heroku create
 $ git push heroku master
 $ heroku run python manage.py migrate
 $ heroku open
 ```
 or
 [![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)

    <h1>Getting Started with Python on Heroku</h1>
    <p>This is a sample Python application deployed to Heroku. It's a reasonably simple app - but a good foundation for understanding how to get the most out of the Heroku platform.</p>

    To deploy your own copy, and learn the fundamentals of the Heroku platform, head over to the <a href="https://devcenter.heroku.com/articles/getting-started-with-python" class="alert-link">Getting Started with Python on Heroku</a> tutorial.

      <h3><span class="glyphicon glyphicon-info-sign"></span> How this sample app works</h3>
      <ul>
        <li>This app was deployed to Heroku, either using Git or by using <a href="https://github.com/heroku/python-getting-started">Heroku Button</a> on the repository.</li>
        <li>When Heroku received the source code, it fetched all the dependencies in the <a href="https://github.com/heroku/python-getting-started/blob/master/Pipfile">Pipfile</a>, creating a deployable slug.</li>
        <li>The platform then spins up a dyno, a lightweight container that provides an isolated environment in which the slug can be mounted and executed.</li>
        <li>You can scale your app, manage it, and deploy over <a href="https://addons.heroku.com/">150 add-on services</a>, from the Dashboard or CLI.</li>
      </ul>
    </div>
    <div class="col-md-6">
      <h3><span class="glyphicon glyphicon-link"></span> Next Steps</h3>
      <ul>
        <li>If you are following the <a href="https://devcenter.heroku.com/articles/getting-started-with-python">Getting Started</a> guide, then please head back to the tutorial and follow the next steps!</li>
        <li>If you deployed this app by deploying the Heroku Button, then in a command line shell, run:</li>
        <ul>
          <li><code>git clone https://github.com/heroku/python-getting-started.git</code> - this will create a local copy of the source code for the app</li>
          <li><code>cd python-getting-started</code> - change directory into the local source code repository</li>
          <li><code>heroku git:remote -a &lt;your-app-name></code> - associate the Heroku app with the repository</li>
          <li>You'll now be set up to run the app locally, or <a href="https://devcenter.heroku.com/articles/getting-started-with-python#push-local-changes">deploy changes</a> to Heroku</li>
        </ul>
      </ul>
