+
+In this tutorial, we have learnt to,
+
 
-  You should now be able to --
 \begin{itemize}
-\item make sets from lists
-\item input sets directly
-\item perform operations like union, intersection, symmetric difference
-\item check if a subset of another
-\item check containership, length and other properties similar to lists
+\item Know what happens when we import a module.
+\item Use a script as a module.
+\item Write test functions using the ``\_\_name\_\_'' idiom.
 \end{itemize}

+\item The script ``utils.py'' is in one of locations of PYTHONPATH and contains
+    the following code
+\lstset{language=Python}
+\begin{lstlisting}
+def show(x):
+    print x
+
+show("Hello World")
+
+if __name__ == "__main__":
+
+    show("Hello Test")
+\end{lstlisting}
+  How do you use the ``show'' function after doing ``import utils''
+\begin{itemize}
+\item utils.show(``hey'')
+\item show(``hey'')
+\item utils.py.show(``hey'')
+\item utils.py.show.py(``hey'')
