About this template

Goals

cookiecutter-python-package is an opinionated Cookiecutter template for Python projects with a focus on:

• long-term maintainability of the generated project (think decades, not years);

• reliability through step-by-step instructions, enabling users to build, run, and work on the generated project on diverse platforms;

• using the latest Python language and API features; and

• building runnable programs, not libraries.

What you put in

The template allows you to specify:

• project title, slug, description and version;

• a name for the first module;

• both an author name and a copyright holder name;

• the author’s email address;

• a project license (Apache 2.0 or proprietary license);

• a Python major/minor version;

• whether to include the fire package, which makes it easier to develop a CLI tool;

• whether to include the jupyter package; and

• whether to include the pandas package.

What you get out of it

The Cookiecutter template will give you:

• a README.md file with detailed instructions;

• a LICENSE file;

• the root Python package, located at {{ cookiecutter.python_package_name }};

• the first module, located in the root Python package;

• a global settings file that all modules can import;

• a pyproject.toml file and an initial Poetry lockfile;

• a default linter configuration;

• a pytest script and default configuration;

• a pdoc setup to generate documentation;

• a set of poe tasks for running the module scripts, tests and the linter (for details, run poetry run poe tasks);

• a virtual environment with initial dependencies installed and ready to use;

• a .gitattributes file;

• a .gitignore file;

• an .editorconfig file; and

• settings for Visual Studio Code integration.

Using cookiecutter-python-package

System requirements

To use this Cookiecutter template, you need:

1. The Python version manager pyenv.

2. A system-wide Python installation.

3. Cookiecutter version 2.6.0 or newer.

4. The Python dependency manager poetry.

Installing pyenv

You need the Python version manager pyenv so you can set up your generated package, and to make sure you can always keep that package up and running, regardless of your system Python.

Installing pyenv on Windows

While pyenv doesn’t support Windows, you can use a drop-in replacement called pyenv-win.

To install pyenv-win on Windows, go to github.com/pyenv-win/pyenv-win and follow one of the installation methods.

Installing pyenv on Linux

To install pyenv on Linux or WSL2, first make sure Python 3 is installed. Then follow the Basic GitHub Checkout method described at github.com/pyenv/pyenv.

Installing pyenv on macOS

To install pyenv on macOS, run:

brew install pyenv

Checking your system-wide pyenv installation

To verify your pyenv is working, run:

pyenv --version

Checking your system-wide Python installation

Make sure you have Python 3.8 or higher installed on your system and available in your PATH.

To check, run:

python --version

If that fails, try:

python3 --version

Proceed after you’ve confirmed one of those to work.

Installing Cookiecutter

To install Cookiecutter, follow Cookiecutter’s installation instructions.

Installing Poetry

You’ll need poetry to manage the generated Python package.

Installing Poetry on Windows

To install Poetry on Windows, use one of the installation methods described in Poetry’s documentation.

Installing Poetry on Linux

If you’re on Linux or WSL2, use your system package manager to install Poetry.

Alternatively, use one of the installation methods described in Poetry’s documentation.

Installing Poetry on macOS

To install Poetry on macOS, run:

brew install poetry

Checking your Poetry installation

To verify Poetry is working, run:

poetry --version

Basic usage

To run the template generator, make sure you have a working Cookiecutter installation. Then run:

cookiecutter gh:claui/cookiecutter-python-package

Alternative usage

If you use cookiecutter-python-package often, you can add to your .cookiecutterrc an abbreviations section like so:

abbreviations:
    python: https://github.com/claui/cookiecutter-python-package.git

Then, to generate a project, run:

cookiecutter python
