    47 \begin{itemize}

    48 \item invoke the \texttt{ipython} interpreter

    49 \item quit the \texttt{ipython} interpreter

    50 \item navigate in the history of \texttt{ipython}

    51 \item use tab-completion

    52 \item look-up documentation of functions

    53 \item interrupt incomplete or incorrect commands

    60   Type \texttt{ab} and hit tab to see what happens. Next, just type \texttt{a} and

    61   hit tab to see what happens.

    67   \texttt{ab} tab completes to \texttt{abs} and \texttt{a<tab>} gives us a list of all the

    68   commands starting with a.

   109   Try typing \texttt{round(2.484}, and hit enter. and then cancel the command

   110   using Ctrl-C. Then, type the command, \texttt{round(2.484, 2)} and resume

   111   the video.
