I am a heavy user of Jupyter Notebook, both personally for wrapping my head around Open Data, professionally for analysis and reporting, and for education/presentations. So am very comfortable with just spinning up new notebooks all over the show. However, this ends up looking like this… Less than informative and impossible to work out WTF I was doing. Helpfully, there’s a way to change it. In your jupyter_notebook_config.py file (Normally in ~/.jupyter), add the following somewhere sensible ...

Logging functions being called with just a variable and no comment as to what the hell it is logging has functions more than logging.info, use them!
