Python Dev Tools

Needed and up-to-date tools to develop in Python (WORK IN PROGRESS)

Supported Python versions: the same as the classic Python interpreter (CPython)

Documentation

The full documentation can be read at https://python-dev-tools.readthedocs.io.

Installation

In a terminal, run:

$ python3 -m pip install python-dev-tools --user --upgrade

Full documentation on installation: https://python-dev-tools.readthedocs.io/en/latest/installation.html

That's it! Use the provided linter (flake8), formatter (whataformatter) and precommit hook (TODO) where applicable.

Installation with Visual Studio Code

• Follow the installation procedure for python-dev-tools
• Be sure to have the official Python extension installed in VS Code
• Open VS Code from within your activated virtual environment (in fact, make sure that flake8 from python-dev-tools is in your PYTHON_PATH)
• In VS Code, open settings (F1 key, then type "Open Settings (JSON)", then enter)
• Add in the opened JSON file (before the closing }):

"python.linting.enabled": true,
"python.linting.flake8Enabled": true,
"python.linting.flake8Path": "flake8",
"python.formatting.provider": "black",
"python.formatting.blackPath": "whataformatter",
"python.formatting.blackArgs": [],
