+\label{sec-1}
+
+\begin{itemize}
+\item Slicing strings to get sub-strings
+\item Reversing strings
+\item Replacing characters in strings.
+\item Converting strings to upper or lower case
+\item Joining a list of strings
+\end{itemize}

+\begin{frame}
+\frametitle{Question 1}
+\label{sec-2}
+
+  Obtain the sub-string excluding the first and last characters from
+  the string \texttt{s}.
+\end{frame}
+\begin{frame}[fragile]
+\frametitle{Solution 1}
+\label{sec-3}
+
+\begin{verbatim}
+In []:  s[1:-1]
+\end{verbatim}
+\end{frame}
+\begin{frame}
+\frametitle{Question 2}
+\label{sec-4}
+
+  Given a list week, week = \texttt{week = ["sun", "mon", "tue", "wed",   "thu", "fri", "sat"]}. Check if \texttt{s} is a valid name of a day of the
+  week. Change the solution to this problem, to include forms like,
+  SAT, SATURDAY, Saturday and Sat.
+\end{frame}
+\begin{frame}[fragile]
+\frametitle{Solution 2}
+\label{sec-5}
+
+\begin{verbatim}
+In []:  s in week
+In []:  s.lower()[:3] in week
+\end{verbatim}
+\end{frame}
+\begin{frame}
+\frametitle{Question 3}
+\label{sec-6}
+
+  Given \texttt{email} -- \texttt{info@fossee[dot]in}
+
+  Replace the \texttt{[dot]} with \texttt{.} in \texttt{email}
+\end{frame}
+\begin{frame}[fragile]
+\frametitle{Solution 3}
+\label{sec-7}
+
+\begin{verbatim}
+email.replace('[dot], '.')
+print email
+\end{verbatim}
+\end{frame}
+\begin{frame}
+\frametitle{Question 4}
+\label{sec-8}
+
+  From the \texttt{email\_str} that we generated, change the separator to be a
+  semicolon instead of a comma.
+\end{frame}
+\begin{frame}[fragile]
+\frametitle{Solution 4}
+\label{sec-9}

+\frametitle{Summary}
+\label{sec-10}
+
+  You should now be able to --
+\begin{itemize}
+\item Slice strings and get sub-strings out of them
+\item Reverse strings
+\item Replace characters in strings.
+\item Convert strings to upper or lower case
+\item Join a list of strings
+\end{itemize}
