\frametitle{Objectives}
\label{sec-2}
At the end of this tutorial, you will be able to,
\begin{itemize}
\item invoke the \verb~ipython~ interpreter.
\item quit the \verb~ipython~ interpreter.
\item navigate in the history of \verb~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-3}
\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-4}
\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-5}
Look-up the documentation of \texttt{round} and see how to use it
\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}
\begin{enumerate}
\item Type \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)} and resume
the video.
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Summary}
\label{sec-9}
In this tutorial, we have learnt to –
\begin{itemize}
\item invoke the \verb~ipython~ interpreter by typing ipython.
\item quit the \verb~ipython~ interpreter by using \verb~Ctrl-d~.
\item navigate in the history of \verb~ipython~ by using the arrow keys.
\item use tab-completionto work faster.
\item see the documentation of functions using question mark.
\item interrupt using \verb~Ctrl-c~ when we make an error.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-10}
\begin{enumerate}
\item Ipython is a programming similar to Python?
True or False
\item Which key combination quits ``ipython``?
\begin{itemize}
\item Ctrl + C
\item Ctrl + D
\item Alt + C
\item Alt + D
\end{itemize}
\item Which character is used at the end of a command, in Ipython to
display the documentation.
\begin{itemize}
\item under score ($_)$
\item question mark (?)
\item exclamation mark (!)
\item ampersand (\&)
\end{itemize}
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Solution}
\label{sec-11}
\begin{enumerate}
\item False
\item Ctrl + D
\item question mark (?)
\end{enumerate}
\end{frame}
