-\begin{itemize}
-\item Assigning default values to arguments
-\item Calling functions using Keyword arguments
-\item functions in standard library
-\end{itemize}

-\frametitle{Question 1}
-\label{sec-2}
-
-  Redefine the function \texttt{welcome}, by interchanging it's
-  arguments. Place the \texttt{name} argument with it's default value of
-  ``World'' before the \texttt{greet} argument.
-\end{frame}
-\begin{frame}[fragile]
-\frametitle{Solution 1}
-\label{sec-3}
-
-\begin{verbatim}
-def welcome(name="World", greet):
-    print greet, name
-\end{verbatim}
-  We get an error that reads \texttt{SyntaxError: non-default argument   follows default argument}. When defining a function all the
-  argument with default values should come at the end.
-\end{frame}
-\begin{frame}
-\frametitle{Question 2}
-\label{sec-4}
-
-  See the definition of linspace using \texttt{?} and observe how all the
-  arguments with default values are towards the end.
-\end{frame}
-\begin{frame}[fragile]
-\frametitle{Solution 2}
-\label{sec-5}
-
-\begin{verbatim}
-linspace?
-\end{verbatim}
-\end{frame}
-\begin{frame}
-\frametitle{Question 3}
-\label{sec-6}
-
-  Redefine the function \texttt{welcome} with a default value of
-  ``Hello'' to the \texttt{greet} argument. Then, call the function without any
-  arguments. 
-\end{frame}
-\begin{frame}[fragile]
-\frametitle{Solution 3}
-\label{sec-7}
-
-\begin{verbatim}
-def welcome(greet="Hello", name="World"):
-    print greet, name
-
-welcome()
-\end{verbatim}
-\end{frame}
-\begin{frame}
-\frametitle{Summary}
-\label{sec-8}
-
-  You should now be able to --
-\begin{itemize}
-\item define functions with default arguments
-\item call functions using keyword arguments
-\end{itemize}
-\end{frame}
