\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}

\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}

\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}
