1 Creating a linear array:\\

     1 Writing an if/elif/else block:

     2 {\ex \lstinline|    x = linspace(0, 2*pi, 50)|}

     2 \begin{lstlisting}

     3 if condition1:

     4    # do A, B, C

     5 elif condition2:

     6    # do D, E

     7 else:

     8    # do Y, Z

     9 \end{lstlisting}

     4 Plotting two variables:\\

    11 The ternary operator:

     5 {\ex \lstinline|    plot(x, sin(x))|}

    12 {\ex \lstinline|    C if X else Y|} -- Do C if X is True else do Y. 

     6 

     7 Plotting two lists of equal length x, y:\\

     8 {\ex \lstinline|    plot(x, y)|}
