\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}

\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}
