Michael #1: Python 3.14.0 alpha 1 is now available
- First of seven planned alpha releases.
- Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far:
Brian #2: uv supports dependency groups
- we covered dependency groups in episode 406
- as of 0.4.27, uv supports dependency groups
- docs show how to add dependencies with uv add --group
- also “The --dev, --only-dev, and --no-dev flags are equivalent to --group dev, --only-group dev, and --no-group dev respectively.”
- To install a group, uv pip install --group doesn’t work yet.
- It’s waiting for PyPA to decide on an interface for pip, and uv pip will use that interface.
- But sync works.
$ uv init # create a pyproject.toml $ uv add --group foo pytest $ uv venv # create venv $ uv sync --group foo # will install all dependencies, including group "foo"
Michael #3: dive: A tool for exploring each layer in a docker image
- via Mike Fiedler
- Features:
- Show Docker image contents broken down by layer
- Indicate what's changed in each layer
- Estimate "image efficiency"
- Quick build/analysis cycles
- CI Integration
Brian #4: pytest-metadata
- An incredibly useful plugin for adding, you guessed it, metadata, to your pytest results.
- Required for pytest-html but also useful on it’s own
- Adds metadata to
- text output with --verbose
- xml output when using --junit-xml, handy for CI systems that support junit.xml
- Other plugins depend on this and report in other ways, such as pytest-html
- By default, already grabs
- Python version
- Platform info
- List of installed packages
- List of installed pytest plugins
- You can add your own metadata
- You can access all metadata (and add to it) from tests, fixtures, and hook functions via a metadata fixture.
- This is in the Top pytest Plugins list, currently #5.
Extras
Brian:
- I’ve started filtering deprecated plugins from the pytest plugin list.
- I’m also going to start reviewing the list and pulling out interesting plugins as the topic of the next season of Test & Code.
Michael:
- Pillow 11 is out
- pip install deutschland
- Talk Python has a dedicated blog, please subscribe!
