\begin{document}

\begin{frame}
  \titlepage
\end{frame}

\begin{frame}
  \frametitle{Write your details...}
On the top right hand corner please write down the following:
  \begin{itemize}
    \item  Name:
    \item Affliation:
    \item Occupation:
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> x = array([[1,2,3,4],[3,4,2,5]])
  >>> x.shape
  (2, 4)
\end{lstlisting}
Change the shape of \lstinline+x+ to (4,2)
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> x = array([[1,2,3,4]])
\end{lstlisting}
How to change the third element of \lstinline+x+ to 0?
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
What would be the result?
\begin{lstlisting}
  >>> y = arange(3)
  >>> x = linspace(0,3,3)
  >>> x-y
\end{lstlisting}
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> x = array([0, 1, 2, 3])
  >>> x.shape = 2,2
  >>> x
  array([[0, 1],
         [2, 3]])
  >>> x[::2,::2]
\end{lstlisting}
What is the output?
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
What would be the result?
\begin{lstlisting}
  >>> x
  array([[0, 1, 2],
         [3, 4, 5],
         [6, 7, 8]])
  >>> x[::-1,:]
\end{lstlisting}
Hint:
\begin{lstlisting}
  >>> x = arange(9)
  >>> x[::-1]
  array([8, 7, 6, 5, 4, 3, 2, 1, 0])
\end{lstlisting}
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> x
  array([[ 0, 1, 2, 3],
         [ 4, 5, 6, 7],
         [ 8, 9, 10, 11],
         [12, 13, 14, 15]])
\end{lstlisting}
How will you get the following \lstinline+x+?
\begin{lstlisting}
  array([[ 5, 7],
         [ 9, 11]])
\end{lstlisting}
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> x = array(([1,2,3,4],[2,3,4,5]))
  >>> x[-2][-3] = 4
  >>> x
\end{lstlisting}
What will be printed?
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
What would be the output?
\begin{lstlisting}
  >>> y = arange(4)
  >>> x = array(([1,2,3,2],[1,3,6,0]))
  >>> x + y
\end{lstlisting}
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
\begin{lstlisting}
  >>> line = plot(x, sin(x))
\end{lstlisting}
Use the \lstinline+set_linewidth+ method to set width of \lstinline+line+ to 2.
\end{frame}

\begin{frame}[fragile]
\frametitle{\incqno }
What would be the output?
\begin{lstlisting}
  >>> x = arange(9)
  >>> y = arange(9.)
  >>> x == y
\end{lstlisting}
\end{frame}
