Basic Python Project Files09 Jan 2016
I don’t use project templates like cookiecutter. I’m sure they’re fine, but when I start a new project I like to get a cup of coffee, go to my zen place and manually create the workspace. It gets me in the right place to code. Here’s the thing, there is a right way to set up a Python project. Plus, I have a particular style for my repositories — particularly how I use Creative Commons Flickr photos as the header for my README files.
Here’s my primary structure for a project with a primary Python module called “foo”:
$ project . ├── .gitignore ├── .travis.yml ├── bin | └── app.py ├── docs | ├── images | | └── banner.jpg | └── index.md ├── fixtures ├── foo | └── __init__.py ├── LICENSE.txt ├── Makefile ├── mkdocs.yml ├── README.md ├── requirements.txt ├── setup.py └── tests └── __init__.py
So, that’s actually a lot of files! Maybe I should put myself into copy-and-paste land else my coffee get cold while I’m doing this.
Make and Dependencies
Makefile essentially shows how I clean up after myself and run tests, as well as publish to GitHub Pages if I have a subdirectory with HTML for that environment. The requirements are just requirements that I have in basically every single project that I create.
Python modules should be well versioned, especially as I prefer to have good numbering for GitHub releases. Occasionally I will create an actual
version.py in the root of my module, but more often than not, I just stick it into the
__init__.py of the module.
To “version bump” as it were, I simply modify the information in
__version_info__ by updating the release numbers. I also think that someday there is probably also a way to do this automatically or with a version bump script.
Note that these files are named for easy location in Gist, not the names of the actual files in the Repository.
My labels in the Github Issues are defined in the blog post: How we use labels on GitHub Issues at Mediocre Laboratories. I really like adding both a “type” and “priority” to every one of my cards. Makes issue management so much easier.
I also now tend to use both a master and a develop branch, such that my branches are setup in a typical production/release/development cycle as described in A Successful Git Branching Model. A typical workflow is as follows:
Select a card from the dev board - preferably one that is “ready” then move it to “in-progress”.
Create a branch off of develop called “feature-[feature name]”, work and commit into that branch.
~$ git checkout -b feature-myfeature develop
Once you are done working (and everything is tested) merge your feature into develop.
~$ git checkout develop ~$ git merge --no-ff feature-myfeature ~$ git branch -d feature-myfeature ~$ git push origin develop
Repeat. Releases will be routinely pushed into master via release branches, then deployed to the server.
Pull requests will be reviewed when the Travis-CI tests pass, so including tests with your pull request is ideal!
And finally, here is some Markdown that I typically use for the README:
Ok, that’s all the project templates for now!
