\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}

\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.)

\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}
