* 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!
