* 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
