\begin{itemize}
\item invoke the \texttt{ipython} interpreter
\item quit the \texttt{ipython} interpreter
\item navigate in the history of \texttt{ipython}
\item use tab-completion
\item look-up documentation of functions
\item interrupt incomplete or incorrect commands
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Question 1}
\label{sec-2}

  Type \texttt{ab} and hit tab to see what happens. Next, just type \texttt{a} and
  hit tab to see what happens.
\end{frame}
\begin{frame}
\frametitle{Solution 1}
\label{sec-3}

  \texttt{ab} tab completes to \texttt{abs} and \texttt{a<tab>} gives us a list of all the
  commands starting with a.
\end{frame}
\begin{frame}
\frametitle{Question 2}
\label{sec-4}

  Look-up the documentation of \texttt{round} and see how to use it.
\end{frame}
\begin{frame}
\frametitle{Solution 2}
\label{sec-5}

  \texttt{round?}
\end{frame}
\begin{frame}[fragile]
\frametitle{Question 3}
\label{sec-6}

  Check the output of
\lstset{language=Python}
\begin{lstlisting}
round(2.48)
round(2.48, 1)
round(2.48, 2)

round(2.484)
round(2.484, 1)
round(2.484, 2)
\end{lstlisting}
  Look-up the documentation of \texttt{round} and see how to use it.
\end{frame}
\begin{frame}
\frametitle{Solution 3}
\label{sec-7}

  We get 2.0, 2.5 and 2.48, which are what we expect. 
\end{frame}
\begin{frame}
\frametitle{Question 4}
\label{sec-8}

  Try typing \texttt{round(2.484}, and hit enter. and then cancel the command
  using Ctrl-C. Then, type the command, \texttt{round(2.484, 2)} and resume
  the video.
\end{frame}

\frametitle{Summary}
\label{sec-10}

\begin{itemize}
\item invoking and quitting the \texttt{ipython} interpreter
\item navigating the history
\item using tab-completion to work faster
\item looking-up documentation using \texttt{?}
\item sending keyboard interrupts using \texttt{Ctrl-C}
\end{itemize}
