\frametitle{Outline}
\label{sec-1}
\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}
\begin{frame}[fragile]
\frametitle{Solution 4}
\label{sec-9}
\lstset{language=Python}
\begin{lstlisting}

\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}
