* Objectives
  At the end of this tutorial, you will be able to, 
  - Create lists
  - Access list elements
  - Append elements to lists
  - Delete elements from lists

* Exercise 1 
  - What happens when you do nonempty[-1].

* Exercise 2
  - What is the syntax to get the element 'and' 
     in the list,listinlist ?
  - How would you get 'and' using negative indices?

* Solution 2
  
#+begin_src python
  
  listinlist[1]
  listinlist[-5]

#+end_src python
* Exercise 3

  - Remove the third element from the list, listinlist.   

  - Remove 'and' from the list, listinlist.

* Solution 3
#+begin_src python
  
  del(listinlist[2])
  listinlist.remove('and')

#+end_src python
* Summary
  In this tutorial, we have learnt to –
  - Create lists.  
  - Access lists using their index numbers.
  - Append elements to list using the function ``append``.
  - Delete Element from lists by specifying the index number of the
    element to be deleted in the ``del`` function.  
  - Delete element from list by content using ``remove`` function.  
  - Find out the list length using the ``len`` function.
* Evaluation
  1. How do you create an empty list? 
  2. Can you have a list inside a list ? 
  3. How would you access the end of a list without finding its length?
* Solutions
  1. empty=[]
  2. Yes\\
     list\_in\_list=[2.3,[2,4,6],'string,'all datatypes can be there']
  3. Using negative indices\\
     nonempty = ['spam', 'eggs', 100, 1.234]\\
     nonempty[-1]
