* Outline

  - Defining Sets

  - Operations on sets

* Question 1

  Given a list of marks, ~marks = [20, 23, 22, 23, 20, 21, 23]~ list

  all the duplicates

* Solution 1

  #+begin_src python

    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_src

* Summary

  You should now be able to --

  + make sets from lists

  + input sets directly

  + perform operations like union, intersection, symmetric difference

  + check if a subset of another

  + check containership, length and other properties similar to lists

* Thank you!
