+
+Hello friends and welcome to the tutorial on "Getting started with
+lists".
+
+.. L2
+
+{{{ Show slide with objectives }}}
+
+.. R2
 
 In this tutorial we will be getting acquainted with a python data
-structure called lists.  We will learn ::
+structure called lists.  
+At the end of this tutorial, you will be able to, 
  
- * How to create lists
- * Structure of lists
- * Access list elements
- * Append elements to lists
- * Delete elements from lists
+ 1. Create lists
+ #. Access list elements
+ #. Append elements to lists
+ #. Delete elements from lists
 
-List is a compound data type, it can contain data of mutually
-different datatypes. List is also a sequence data type, all the
-elements are arranged in a given order.
+.. R3
 
-.. #[[Anoop: "all the elements are in order and **there** order has a
-   meaning." - I guess something is wrong here, I am not able to
-   follow this.]]
+List is a compound data type, it can contain data of mutually
+different datatypes. List is also a sequence data type where all the
+elements are arranged in a specific order.
 
-We will first create an empty list with no elements. On your IPython
-shell type ::
+Start the ipython interpreter and first create an empty list with no elements. 
 
-   empty = [] 
-   type(empty)
+.. L3
+::   
    
+    ipython
+    empty = [] 
+    type(empty)
 
+.. R4
+  
 This is an empty list without any elements.
 
-.. #[[Anoop: the document has to be continous, without any
-   subheadings, removing * Filled lists]]
+Let us now see how to define a non-empty list. 
 
-Lets now see how to define a non-empty list. We do it as,::
+.. L4
+::
 
-     nonempty = ['spam', 'eggs', 100, 1.234]
+    nonempty = ['spam', 'eggs', 100, 1.234]
+
+.. R5
 
 Thus the simplest way of creating a list is typing out a sequence 
 of comma-separated values (or items) between two square brackets. 
 
 As we can see lists can contain different kinds of data. In the
 previous example 'spam' and 'eggs' are strings whereas 100 and 1.234 are
-integer and float respectively. Thus we can put elements of different types in
+integer and float respectively. Thus we can put elements of different datatypes in
 lists including lists itself. This property makes lists heterogeneous
 data structures.
 
-.. #[[Anoop: the sentence "Thus list themselves can be one of the
-   element types possible in lists" is not clear, rephrase it.]]
+Let us include a list within a list. 
+
+.. L5
+::
 
-Example ::
+    listinlist=[[4,2,3,4],'and', 1, 2, 3, 4]
 
-      listinlist=[[4,2,3,4],'and', 1, 2, 3, 4]
+.. R6
 
 We access an element of a list using its corresponding index. Index of
 the first element of a list is 0. So for the list nonempty, nonempty[0] 
 gives the first element, nonempty[1] the second element and so on and 
-nonempty[3] the last element. ::
+nonempty[3] the last element. 
+
+.. L6
+::
+
+    nonempty[0] 
+    nonempty[1] 
+    nonempty[3]
+
+.. L7
 
-	    nonempty[0] 
-	    nonempty[1] 
-	    nonempty[3]
+{{{ Switch to the slide Question 1 }}}
 
-Following is an exercise that you must do. 
+.. R7
 
-%% %% What happens when you do nonempty[-1]. 
+Pause the video here, try out the following exercise and resume the video.
 
-Please, pause the video here. Do the exercise and then continue.  
+What happens when you do nonempty[-1]. 
 
-.. #[[Anoop: was negative indices introduced earlier, if not may be we
-   can ask them to try out nonempty[-1] and see what happens and then
-   tell that it gives the last element in the list.]]
+.. L8
+
+{{{ Switch to the terminal }}}
+::
+
+    nonempty[-1]
+
+.. R8
 
 As you can see you get the last element which is 1.234.
 
+.. L9
+::
+    
+    nonempty[-2] 
+    nonempty[-4]
 
-In python negative indices are used to access elements from the end::
-   
-   nonempty[-1] 
-   nonempty[-2] 
-   nonempty[-4]
+.. R9
 
--1 gives the last element which is the 4th element , -2 second to last
-and -4 gives the fourth from the last which, in this case,  is the first element.
+In python negative indices are used to access elements from the end.
+-1 gives the last element which is the 4th element , -2 gives second element to last
+and -4 gives the fourth from the last which, in this case, is the first element.
 
-We can append elements to the end of a list using the method append. ::
+.. R10
 
-   nonempty.append('onemore') 
-   nonempty
-   nonempty.append(6) 
-   nonempty
+We can also append elements to the end of a list using the method ``append``. 
+
+.. L10
+::
+
+    nonempty.append('onemore') 
+    nonempty
+    nonempty.append(6) 
+    nonempty

-Using len function we can check the number of elements in the list
-nonempty. In this case it is 6 ::

 Just like we can append elements to a list we can also remove them.

+The other way is removing element by content. Lets say

+ 1. 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 ``len`` function.
 
- * We learned how to create lists.  
- * How to access lists.
- * Append elements to list.
- * Delete Element from list.  
- * And Checking list length.

+
+Here are some self assessment questions for you to solve
+
+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?
+
+.. L24
+
+{{{solution of self assessment questions on slide}}}
+
+.. R24
+
+And the answers,
+
+1. We create an empty list just by leaving the space inside the square brackets empty.
+::
+
+    empty=[]
+
+2. Yes.List can contain all the other data types, including list.
+   Here is an example
+::
+
+    list_in_list=[2.3,[2,4,6],'string,'all datatypes can be there']
+
+3. Using negative indices, we can access the list from the end using negative indices.
+   This is an example
+::
 
+    nonempty = ['spam', 'eggs', 100, 1.234]
+    nonempty[-1]
