* Can you find the history of commands you've run in Jupyter notebook in the same way one might from the command line? * You can use the Jupyter notebook magic [%history command](https://ipython.readthedocs.io/en/stable/interactive/magics.html#magic-history) * If you had a data frame with named index values (as opposed to a range of integers), how would you refer to specific rows with the `loc` interface? * `loc` supports indexing by named index values. See the "Getting values" section of [the pandas documentation for loc](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.loc.html)
