PyClean

Bytecode is opcodes for the Python Virtual Machine. The *.pyc files and __pycache__ folders in your directory tree. On Debian there's pyclean to clean it all up when developing. We need to make this available on all platforms.

1. PyClean PyClean Clean up your Python bytecode & more. PyCon X, Firenze 2019 PyCon X, Firenze 2019 pip install pyclean
2. PyClean PyClean installed on Debian via python-minimal pyclean py3clean pypyclean

9. pip3 install pyclean Code duplication Debian only + dependencies No PyPy3 No tests Limited benefit What's broken? What's broken?
10. How could we use it? How could we use it? tox # runs tests and cleans up afterwards # tox.ini [testenv:clean] commands = py3clean {toxinidir} find . ­name foo ­delete rm ­rf .pytest_cache/ .tox/ *.egg­info whitelist_externals = py3clean find rm
