Simple example of a good project structure with pytest and sphinx implemented

• Good pytest practises: http://pytest.org/latest/goodpractises.html
• General Python testing information: http://pythontesting.net/start-here/
• Directory structure and getting started with writing a setup.py: https://pythonhosted.org/an_example_pypi_project/setuptools.html
• Writing a Python project from scratch: http://www.jeffknupp.com/blog/2013/08/16/open-sourcing-a-python-project-the-right-way/
• Getting started with Sphinx: https://pythonhosted.org/an_example_pypi_project/sphinx.html

• Install the requirements by typing

pip install -r requirements.txt

• As recommended by http://pytest.org/latest/goodpractises.html: no __init__.py file is included in the tests folder.
• To run the tests, you need to run the command:

pip install -e .   # install package using setup.py in editable mode

• Then run the tests using

py.test

• The documentation is built on Sphinx.
• The Car class contains docstrings in 3 different styles:
  • Googley
  • Sphinxy
  • numpydoc
• To build HTML documentation:

cd doc
make html

• To build LaTeX documentation:

cd doc
make latex
cd build/latex
make

The main project directory contains two files called func_1.py and func_2.py. They contain two useless functions called avg and dim which give the mean and shape of a given vector, respectively. In order to use these functions in other projects the __init__.py file requires the following lines

from .func_1 import *                                                           
from .func_2 import *

The __init__.py file is executed when the project is imported so these functions become available.

The steps are as follows:

• Install the package by running $ pip install -e . in the root directory.
• In your project/iPython, import as normal: import mean as mean.
• Can now use these function as mean.avg([1,2,3]) which returns 3.0.
