The Python platform uses Python 2.7.x.

If you just run a git push or tsuru app-deploy of your code, tsuru will try to download all of your depencies using requirements.txt or setup script. You can customize this behavior, see the next section for more details.

There are two ways to list the applications dependencies: requirements.txt or setup.py. The priority order is: requirements -> setup. The file should be in the root of deploy files.

You can define a file called requirements.txt that list all pip dependencies of your application, each line represents one dependency, here's an example:

$ cat requirements.txt
Flask==0.10.1
gunicorn==19.3.0

You can also define the setup script to list your depencies, here's an example:

$ cat setup.py
from setuptools import setup, find_packages
setup(
	name="app-name",
	packages=find_packages(),
	description="example",
	include_package_data=True,
	install_requires=[
    	"Flask==0.10.1",
    	"gunicorn==19.3.0",
	],
)

After invokin git push or tsuru app-deploy, tsuru will receive your code and tell the platform to install all the depencies using pip install -r requirements.txt or pip instal -e ./.
