SQL formatting

To enable SQL formatting, install jupysql:

pip install jupysql --upgrade

Then, a “Format SQL” button will appear in JupyterLab:

Click on “Format SQL” and you’ll see that the SQL cell below is formatted!

from pathlib import Path
from urllib.request import urlretrieve

if not Path("penguins.csv").is_file():
    urlretrieve(
        "https://raw.githubusercontent.com/mwaskom/seaborn-data/master/penguins.csv",
        "penguins.csv",
    )
