\frametitle{Objectives}
\label{sec-2}
At the end of this tutorial, you will be able to,
\begin{itemize}
\item use the ``for'' loop.
\item use the ``while'' loop.
\item Use ``break'', ``continue'' and ``pass'' statements to play around
with loops.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Pre-requisite}
\label{sec-3}
Spoken tutorial on -
\begin{itemize}
\item Getting started with \verb~for~.
\item Conditionals.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Exercise 1}
\label{sec-4}
Write a \verb~while~ loop to print the squares of all the even
numbers below 10.
\end{frame}
\begin{frame}
\frametitle{Exercise 2}
\label{sec-5}
Write a \verb~for~ loop to print the squares of all the even numbers
below 10.
\end{frame}
\begin{frame}
\frametitle{Exercise 3}
\label{sec-6}
Using the \verb~continue~ keyword, modify the \verb~for~ loop, with the range ``range(2,10,2)'', to print the
squares of even numbers below 10, which are multiples of 4.\\
(Do not modify the range function call.)
\end{frame}

\frametitle{Summary}
\label{sec-7}
In this tutorial, we have learnt to,
\begin{itemize}
\item Iterate over a sequence using ``for'' and ``while'' loops.
\item Break out of loops using ``break'' statement.
\item Skip iterations using ``continue'' statement.
\item Use the ``pass'' statement in a loop.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-8}
\begin{enumerate}
\item Given ``range(1,4)'' \\ Write a code to print only the number 1.
\vspace{12pt}
\item Which statement do you use to skip iterations.
\begin{itemize}
\item break
\item pass
\item continue
\end{itemize}
\end{enumerate}
\end{frame}
\begin{frame}[fragile]
\frametitle{Solutions}
\label{sec-9}
\begin{enumerate}
\item \lstset{language=Python}
\begin{lstlisting}
for i in range(1,4):
print i
break
\end{lstlisting}
