\frametitle{Outline}
\label{sec-1}
\begin{itemize}
\item Retrieving ipython history
\item Viewing a part of the history
\item Saving (relevant) parts of the history to a file
\item Running a script from within ipython
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Question 1}
\label{sec-2}
Read through the documentation of \texttt{\%hist} and find out how to list
all the commands between 5 and 10
\end{frame}
\begin{frame}[fragile]
\frametitle{Solution 1}
\label{sec-3}
\lstset{language=Python}
\begin{lstlisting}
In []: %hist 5 10
\end{lstlisting}
\end{frame}
\begin{frame}
\frametitle{Question 2}
\label{sec-4}
Change the label on y-axis to ``y'' and save the lines of code
accordingly
\end{frame}
\begin{frame}[fragile]
\frametitle{Solution 2}
\label{sec-5}
\lstset{language=Python}
\begin{lstlisting}
In []: ylabel("y")
In []: %save /home/fossee/example_plot.py 1 3-6 10
\end{lstlisting}
\end{frame}
\begin{frame}
\frametitle{Question 3}
\label{sec-6}
Use \texttt{\%hist} and \texttt{\%save} and create a script that has show in it and
run it to produce and show the plot.
\end{frame}
\begin{frame}[fragile]
\frametitle{Solution 3}
\label{sec-7}
\lstset{language=Python}
\begin{lstlisting}
In []: %hist 20
In []: %save /home/fossee/show_included.py 1 3-6 8 10 13
In []: %run -i /home/fossee/show_included.py
\end{lstlisting}
\end{frame}
\begin{frame}
\frametitle{Question 4}
\label{sec-8}
Run the script without using the -i option. Do you find any
difference?
\end{frame}
\begin{frame}
\frametitle{Solution 4}
\label{sec-9}
We see that it raises \texttt{NameError} saying the name \texttt{linspace} is not
found.
\end{frame}
\begin{frame}
\frametitle{Summary}
\label{sec-10}
\begin{itemize}
\item Retreiving history using \texttt{\%hist} command
\item Vieweing only a part of history by passing an argument to \%hist
\item Saving the required lines of code in required order using \%save
\item Using \%run -i command to run the saved script
\end{itemize}
