\frametitle{Question 1}
\label{sec-2}

  Given a list of marks, \texttt{marks = [20, 23, 22, 23, 20, 21, 23]} list
  all the duplicates

\frametitle{Solution 1}
\label{sec-3}

\lstset{language=Python}
\begin{lstlisting}
marks = [20, 23, 22, 23, 20, 21, 23] 
marks_set = set(marks)
for mark in marks_set:
    marks.remove(mark)

# we are now left with only duplicates in the list marks
duplicates = set(marks)
\end{lstlisting}

\frametitle{Summary}
\label{sec-4}

  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
\end{itemize}
