    52 

    53 \begin{frame}

    54   \frametitle{Write your details...}

    55 On the top right hand corner please write down the following:

    56   \begin{itemize}

    57     \item  Name:

    58     \item Affliation:

    59     \item Occupation:

    60   \end{itemize}

    61 \end{frame}

    62 

    63 \begin{frame}[fragile]

    64 \frametitle{\incqno }

    65 \begin{lstlisting}

    66   >>> x = array([[1,2,3,4],[3,4,2,5]])

    67   >>> x.shape

    68   (2, 4)

    69 \end{lstlisting}

    70 Change the shape of \lstinline+x+ to (4,2)

    71 \end{frame}

    72 

    73 \begin{frame}[fragile]

    74 \frametitle{\incqno }

    75 \begin{lstlisting}

    76   >>> x = array([[1,2,3,4]])

    77 \end{lstlisting}

    78 How to change the third element of \lstinline+x+ to 0?

    79 \end{frame}

    80 

    81 \begin{frame}[fragile]

    82 \frametitle{\incqno }

    83 What would be the result?

    84 \begin{lstlisting}

    85   >>> y = arange(3)

    86   >>> x = linspace(0,3,3)

    87   >>> x-y

    88 \end{lstlisting}

    89 \end{frame}

    90 

    91 \begin{frame}[fragile]

    92 \frametitle{\incqno }

    93 \begin{lstlisting}

    94   >>> x = array([0, 1, 2, 3])

    95   >>> x.shape = 2,2

    96   >>> x

    97   array([[0, 1],

    98          [2, 3]])

    99   >>> x[::2,::2]

   100 \end{lstlisting}

   101 What is the output?

   102 \end{frame}

   103 

   104 \begin{frame}[fragile]

   105 \frametitle{\incqno }

   106 What would be the result?

   107 \begin{lstlisting}

   108   >>> x

   109   array([[0, 1, 2],

   110          [3, 4, 5],

   111          [6, 7, 8]])

   112   >>> x[::-1,:]

   113 \end{lstlisting}

   114 Hint:

   115 \begin{lstlisting}

   116   >>> x = arange(9)

   117   >>> x[::-1]

   118   array([8, 7, 6, 5, 4, 3, 2, 1, 0])

   119 \end{lstlisting}

   120 \end{frame}

   121 

   122 \begin{frame}[fragile]

   123 \frametitle{\incqno }

   124 \begin{lstlisting}

   125   >>> x

   126   array([[ 0, 1, 2, 3],

   127          [ 4, 5, 6, 7],

   128          [ 8, 9, 10, 11],

   129          [12, 13, 14, 15]])

   130 \end{lstlisting}

   131 How will you get the following \lstinline+x+?

   132 \begin{lstlisting}

   133   array([[ 5, 7],

   134          [ 9, 11]])

   135 \end{lstlisting}

   136 \end{frame}

   137 

   138 \begin{frame}[fragile]

   139 \frametitle{\incqno }

   140 \begin{lstlisting}

   141   >>> x = array(([1,2,3,4],[2,3,4,5]))

   142   >>> x[-2][-3] = 4

   143   >>> x

   144 \end{lstlisting}

   145 What will be printed?

   146 \end{frame}

   147 

   148 \begin{frame}[fragile]

   149 \frametitle{\incqno }

   150 What would be the output?

   151 \begin{lstlisting}

   152   >>> y = arange(4)

   153   >>> x = array(([1,2,3,2],[1,3,6,0]))

   154   >>> x + y

   155 \end{lstlisting}

   156 \end{frame}

   157 

   158 \begin{frame}[fragile]

   159 \frametitle{\incqno }

   160 \begin{lstlisting}

   161   >>> line = plot(x, sin(x))

   162 \end{lstlisting}

   163 Use the \lstinline+set_linewidth+ method to set width of \lstinline+line+ to 2.

   164 \end{frame}

   165 

   166 \begin{frame}[fragile]

   167 \frametitle{\incqno }

   168 What would be the output?

   169 \begin{lstlisting}

   170   >>> x = arange(9)

   171   >>> y = arange(9.)

   172   >>> x == y

   173 \end{lstlisting}
