\section{Starting up Ipython}
\begin{frame}[fragile]
\frametitle{Starting up \ldots}

\begin{lstlisting}
  $ ipython -pylab  
\end{lstlisting} %$
\end{block}
\begin{lstlisting}     
  In []: print "Hello, World!"
  Hello, World!
\end{lstlisting}
Exiting
\begin{lstlisting}     
  In []: ^D(Ctrl-D)
  Do you really want to exit([y]/n)? y
\end{lstlisting}
\end{frame}

\section{Loops - Indentation and Breaking out of loops}
\begin{frame}[fragile]
\frametitle{Loops}
Breaking out of loops
\begin{lstlisting}     
  In []: while True:
    ...:     print "Hello, World!"
    ...:     
  Hello, World!
  Hello, World!^C(Ctrl-C)
  ------------------------------------
  KeyboardInterrupt                   

\end{lstlisting}
\emphbar{\alert{Indentation: Notice the 4 spaces before\\} \typ{print "Hello, World!"}}
\end{frame}

\section{Saving Commands}
\begin{frame}[fragile]
\frametitle{History and Saving of Commands}
\begin{itemize}
\item \typ{\%hist} gives complete history of commands in a session
\item \typ{\%save} can be used to save the commands
\end{itemize}
\begin{block}{Careful about errors!}
  \kwrd{\%hist} will contain the errors as well,\\
  so be careful while selecting line numbers.
\end{block}

\section{Scite - How to}
\begin{frame}[fragile]
  \frametitle{Scite - How to \ldots}
  \begin{itemize}
  \item Opening scite - run scite from command line
  \item Type the contents
  \item Saving the file with a filename \alert{File $\rightarrow$ Save as}
  \item Exiting the editor  \alert{File $\rightarrow$ Exit}
  \item To open an existing file: \alert{File $\rightarrow$ Open}
  \end{itemize}
\end{frame}

\section{Summary}
\begin{frame}[fragile]
  \frametitle{What did we learn?}
