\frametitle{Objectives}
\label{sec-1}
At the end of this tutorial, you will be able to --
\begin{itemize}
\item invoke the \texttt{ipython} interpreter
\item quit the \texttt{ipython} interpreter
\item navigate the \texttt{ipython} session history
\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}
\begin{enumerate}
\item Type \texttt{ab} and hit tab to see what happens.
\item Next, just type \texttt{a} and hit tab to see what happens.
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Solution 1}
\label{sec-3}
\begin{enumerate}
\item \texttt{ab} tab completes to \texttt{abs}
\item \texttt{a<tab>} gives us a list of all the commands starting
with a.
\end{enumerate}
\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
\begin{verbatim}
round(2.48)
round(2.48, 1)
round(2.48, 2)
round(2.484)
round(2.484, 1)
round(2.484, 2)
\end{verbatim}
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}
\begin{enumerate}
\item Try typing \texttt{round(2.484}, and hit enter. and then cancel
the command using Ctrl-C.
\item Then, type the command, \texttt{round(2.484, 2)}
\end{enumerate}
\end{frame}
\begin{frame}[fragile]
\frametitle{Solution 4}
\label{sec-9}
\begin{verbatim}
round(2.484
^C
round(2.484, 2)
\end{verbatim}

\frametitle{Summary}
\label{sec-10}
In this tutorial, we have learnt to --
\begin{itemize}
\item invoke the IPython interpreter using \texttt{ipython} command
\item quit \texttt{ipython} using \texttt{Ctrl-D}
\item navigate the history using arrow keys
\item use tab-completion to work faster
\item look up documentation of functions using \texttt{?}
\item send keyboard interrupts using \texttt{Ctrl-C}
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-11}
\begin{itemize}
\item \texttt{ipython} is a programming language similar to Python \\
True or False\\
\vspace*{20pt}
\item Which key combination quits \texttt{ipython}?\\
\vspace*{10pt}
* Ctrl + C\\
* Ctrl + D\\
* Alt + C\\
* Alt + D\\
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-12}
\begin{itemize}
\item Which character is used at the end of a command, in \texttt{ipython} to display the documentation\\
\vspace*{10pt}
* \_\\
* ?\\
* !\\
* \&\\
\end{itemize}
