Tip

You can also install the libraries with any modern Python package management tool, such as pdm, rye, hatch or any other PEP-517 PEP-518 compliant package manger (basically, not poetry).

2. Launch an IDE, a REPL or a Jupyter notebook to run the katas. For example:

python -m jupyter lab

The notebooks are under the notebooks directory.
