# Heroku Buildpack: Python
|
|
|
|
|
|
This is a [Heroku buildpack](http://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [pip](http://www.pip-installer.org/).
|
|
|
|
This buildpack supports running Django and Flask apps.
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
Example usage:
|
|
|
|
$ ls
|
|
Procfile requirements.txt web.py
|
|
|
|
$ heroku create --buildpack git://github.com/heroku/heroku-buildpack-python.git
|
|
|
|
$ git push heroku master
|
|
...
|
|

|
|
-----> Discovering process types
|
|
Procfile declares types -> (none)
|
|
|
|
You can also add it to upcoming builds of an existing application:
|
|
|
|
$ heroku buildpacks:set heroku/python
|
|
|
|
The buildpack will detect your app as Python if it has the file `requirements.txt` in the root.
|
|
|
|
It will use pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
|
|
|
|
Specify a Runtime
|
|
-----------------
|
|
|
|
You can also specify specific versions of the Python runtime with a `runtime.txt` file:
|
|
|
|
$ cat runtime.txt
|
|
python-3.5.1
|
|
|
|
Runtime options include:
|
|
|
|
- `python-2.7.11`
|
|
- `python-3.5.1`
|
|
- `pypy-4.0.1` (unsupported, experimental)
|
|
- `pypy3-2.4.0` (unsupported, experimental)
|
|
|
|
Other [unsupported runtimes](https://github.com/heroku/heroku-buildpack-python/tree/master/builds/runtimes) are available as well.
