* Objectives
  At the end of this tutorial, you will be able to, 

 - Create sets from lists.
 - Perform union, intersection and symmetric difference operations.
 - Check if a set is a subset of other.
 - Understand various similarities with lists like length and containership.

* Pre-requisite
Spoken tutorial on -
- Getting started with Lists
* Exercise 1
 - Given a list of marks,
 ~marks = [20, 23, 22, 23, 20, 21, 23]~ 
 List all the duplicates
* Summary
 In this tutorial, we have learnt to,

 - Make sets from lists.
 - Perform union, intersection and symmetric difference operations.
   by using the operators `|`, `&` and ` \^ ` respectively.
 - Check if a set is a subset of other using the `<` and `<=` operators.
 - Understand various similarities with lists like length and containership.
* Evaluation
1. If ~a = [1, 1, 2, 3, 3, 5, 5, 8]~. What is set(a)?

   - set([1, 1, 2, 3, 3, 5, 5, 8])
   - set([1, 2, 3, 5, 8])
   - set([1, 2, 3, 3, 5, 5])
   - Error

2. Given,  ~odd = set([1, 3, 5, 7, 9])~ and ~squares = set([1, 4, 9, 16])~. 
    How do you find the symmetric difference of these two sets?


3. ``a'' is a set. how do you check if a variable ``b'' exists in ``a''?
* Solutions
1. set([1, 2, 3, 5, 8])

2. odd ^ squares

3. b in a
