\label{sec-2}
Given a list of marks, \texttt{marks = [20, 23, 22, 23, 20, 21, 23]} list
all the duplicates

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}
