This copies the official Docker Python images approach of stripping the Python test suite after building from source. For Python 3.6.2 this reduces the output from 184MB to 121MB and removes the following directories: ``` .heroku/python/lib/python3.6/tkinter/test .heroku/python/lib/python3.6/ctypes/test .heroku/python/lib/python3.6/unittest/test .heroku/python/lib/python3.6/distutils/tests .heroku/python/lib/python3.6/sqlite3/test .heroku/python/lib/python3.6/lib2to3/tests .heroku/python/lib/python3.6/test ``` For Python 2.7.13 this reduces the output from 127MB to 91MB and removes the following directories: ``` .heroku/python/lib/python2.7/ctypes/test .heroku/python/lib/python2.7/unittest/test .heroku/python/lib/python2.7/distutils/tests .heroku/python/lib/python2.7/bsddb/test .heroku/python/lib/python2.7/lib-tk/test .heroku/python/lib/python2.7/sqlite3/test .heroku/python/lib/python2.7/lib2to3/tests .heroku/python/lib/python2.7/json/tests .heroku/python/lib/python2.7/email/test .heroku/python/lib/python2.7/test ``` Fixes #424.
Heroku Buildpack: Python
This is the official Heroku buildpack for Python apps, powered by pip and other excellent software.
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.
Some Python packages with obscure C dependencies are not compatible.

Deploying a Python application couldn't be easier:
$ ls
Procfile requirements.txt web.py
$ heroku create --buildpack heroku/python
$ git push heroku master
...
-----> Python app detected
-----> Installing python-3.6.2
$ pip install -r requirements.txt

-----> Discovering process types
Procfile declares types -> (none)
A requirements.txt file must be present at the root of your application's repository.
You can also specify the latest production release of this buildpack for upcoming builds of an existing application:
$ heroku buildpacks:set heroku/python
Specify a Python Runtime
Specific versions of the Python runtime can be specified with a runtime.txt file:
$ cat runtime.txt
python-2.7.13
Runtime options include:
