Questions tagged [jupyter-notebook]
The Jupyter Notebook is a web application that provides a frontend to many different languages and interactive shells such as IPython.

DO NOT use this tag on questions regarding code which merely happens to be written using Jupyter Notebooks, use the appropriate language tag instead, e.g. [python], [r].
