What I learned this week⌗

Software⌗

You can run a tool in an ephemeral environment uvx pycowsay 'hello world!'
uvx is an alias for uv tool run
install different python versions uv python install 3.10 3.11 3.12 and pin them in a directory uv python pin 3.11; however, by default, Python versions are automatically downloaded as needed without using uv python install
The .python-version file can be used to create a default Python version request. uv searches for a .python-version file in the working directory and each of its parents. If none is found, uv will check the user-level configuration directory.
Executes standalone scripts with run. echo "print(2+2)" > example.py | uv run example.py
uv pip freeze: List installed packages and their versions.
