\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

\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}
