Brian #1: uv venv --python & uv python
- I was reading this article Python Packaging is Great Now:
uv
is all you need - It’s a little too “look, a silver bullet” for me, but it did point out some cool uv stuff I didn’t know about.
- uv venv venv --python 3.12 creates a virtual environment with Python 3.12,
- even if you didn’t have 3.12 installed on your system already.
- If it doesn’t work, try adding --python-preference managed
- uv python list shows all the python versions on your computer
- There’s quite a few “experimental features”
- run Run a command or script (experimental)
- init Create a new project (experimental)
- add Add dependencies to the project (experimental)
- remove Remove dependencies from the project (experimental)
- sync Update the project's environment (experimental)
- lock Update the project's lockfile (experimental)
- tree Display the project's dependency tree (experimental)
- tool Run and manage tools provided by Python packages (experimental)
- python Manage Python versions and installations (experimental)
- uv venv venv --python 3.12 creates a virtual environment with Python 3.12,
- uv add --dev pytest will add pytest to your dev dependencies.
- uv tree rocks
- uv might not have “solved packaging” (or maybe it might have)
- but it sure is fun to watch the experimentation of different workflows.
Michael #2: Python 3.12.5 released
- Lots of changes, see the release notes
Brian #3: Compile and use dependencies for multiple Python versions in Tox
- Viktor Rimark
- Cool idea to use the {envname}, which specifies the tox environment, in the name of a requirements-dev.txt file name.
- Then add a requirements tox target to generate pip-compile-ed files.
- Now I gotta try doing all of this with uv lock
- Then we need everyone to mod their tools to comply with PEP 571, when/if it’s adopted (covered it last week)
Michael #4: Catalog of Dark Patterns
- Including
- Bait and Switch
- Confirm Shaming
- Disguised Ads
- Roach Motel
- Fake Scarcity
- …
Extras
Brian:
- Recording of Hello, pytest! is done. Editing now. On track for the 19th (or before).
Michael:
- Django 5.1 released
- Python 3.13.0 release candidate 1 released
