Minimum Structure of a Python Project

Here is the structure of a project named tasks_proj

In this project, the setup.py is defined as followed:

"""Minimal setup file for tasks project."""

from setuptools import setup, find_packages

setup(
    name='tasks',
    version='0.1.0',
    license='proprietary',
    description='Minimal Project Task Management',

    author='Brian Okken',
    author_email='Please use pythontesting.net contact form.',
    url='https://pragprog.com/book/bopytest',

    packages=find_packages(where='src'),
    package_dir={'': 'src'},

    install_requires=['click', 'tinydb', 'six'],
    extras_require={'mongo': 'pymongo'},

    entry_points={
        'console_scripts': [
            'tasks = tasks.cli:tasks_cli',
        ]
    },
)

Using such as structure of setup.py, the project can be installed locally using pip

$ cd tasks_proj
$ pip install .         # pip install -e .  (see below for comments on this)

or

$ cd ..
$ pip install --no-chache-dir -e tasks_proj

the -e commands allows you to modify the source code while tasks is installed. Otherwise you will only be able to run the tests against tasks but won’t be able to modify the code.
