Python is a clear and powerful object-oriented programming language, comparable to Perl, Ruby, Scheme, or Java. Its main focus is on readability and standards based approaches.
Use pip to install applications and virtualenv to manage your development environments.
Unless otherwise required use Python 3.5 and if multiple version of support are desired use tox to run tests across multiple python versions. For install instructions go here
Follow pep8 rules, just do it, there are multiple tools but pep8 is probably best used in continuous integration. Tools like pyflakes can offer more hints but oftentimes can be too noisy.
All projects should include README.md files with links to this document, Contributors.md with information about how to contribute and who is contributing, and a license file, MIT preferred. Each project should have a requirements folder containing an apps.txt file in the requirement file format always pin requirements to and use projects which respect semver. Also including a dev.txt requirements file with developer tools can be helpful as well as OS specific scripts.
Applications should be pip installable and once mature added to pypi. This mainly means having a setup.py file in the root of your project.
Documentation should be both inline and external documents stored in the docs/. Sphinx is well understood and popular tool.
Often while working on a project you will end up creating one or more general purpose libraries or applications that best belong in their own repository. To avoid having to reinstall your application to your virtual environment you can use pip to install an editable dependency.
For example if you have a module you are editing in ../my_app and want to have it installed in x-project's virtualenv you could do this.
workon x-project pip install -e ../my_app
This will install my_app into your x-project with a symlink back to the ../my_app directory. If my_app has its own dependencies they will also be installed but not as editable modules.
