+
+Hello friends and welcome to the tutorial on getting started with
+lists.
+
+ {{{ Show the slide containing the outline slide }}}
+
+In this tutorial we will be getting acquainted with a python data
+structure called lists.  We will learn ::
+ 
+ * How to create lists
+ * Structure of 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.
+
+.. #[[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.]]
+
+We will first create an empty list with no elements. On your IPython
+shell type ::
+
+   empty = [] 
+   type(empty)
+   
+
+This is an empty list without any elements.
+
+.. #[[Anoop: the document has to be continous, without any
+   subheadings, removing * Filled lists]]
+
+Lets now see how to define a non-empty list. We do it as,::
+
+     nonempty = ['spam', 'eggs', 100, 1.234]
+
+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
+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.]]
+
+Example ::
+
+      listinlist=[[4,2,3,4],'and', 1, 2, 3, 4]
+
+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[0] 
+	    nonempty[1] 
+	    nonempty[3]
+
+Following is an exercise that you must do. 
+
+%% %% What happens when you do nonempty[-1]. 
+
+Please, pause the video here. Do the exercise and then continue.  
+
+.. #[[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.]]
+
+As you can see you get the last element which is 1.234.
+
+
+In python negative indices are used to access elements from the end::
+   
+   nonempty[-1] 
+   nonempty[-2] 
+   nonempty[-4]
+
+-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.
+
+We can append elements to the end of a list using the method append. ::
+
+   nonempty.append('onemore') 
+   nonempty
+   nonempty.append(6) 
+   nonempty
+   
+Following are  exercises that you must do. 
+
+%% %% What is the syntax to get the element 'and' 
+in the list,listinlist ?
+
+
+%% %% How would you get 'and' using negative indices?
+
+Please, pause the video here. Do the exercise and then continue.  
+
+The solution is on your screen
+
+
+As we can see nonempty is appended with 'onemore' and 6 at the end.
+
+Using len function we can check the number of elements in the list
+nonempty. In this case it is 6 ::
+	 
+	 len(nonempty)
+
+
+
+Just like we can append elements to a list we can also remove them.
+There are two ways of doing it. One is by using index. ::
+
+      del(nonempty[1])
+
+
+
+deletes the element at index 1, i.e the second element of the
+list, 'eggs'. The other way is removing element by content. Lets say
+one wishes to delete 100 from nonempty list the syntax of the command
+would be 
+
+.. #[[Anoop: let x = [1,2,1,3]
+   	     now x.remove(x[2])
+	     still x is [2,1,3] so that is not the way to remove
+	     element by index, it removed first occurrence of 1(by
+	     content) and not based on index, so make necessary
+	     changes]]
+
+::
+
+    nonempty.remove(100)
+
+but what if there were two 100's. To check that lets do a small
+experiment. ::
+
+	   nonempty.append('spam') 
+	   nonempty
+	   nonempty.remove('spam') 
+	   nonempty
+
+If we check now we will see that the first occurence 'spam' is removed
+and therefore `remove` removes the first occurence of the element in the sequence
+and leaves others untouched.
+
+One should remember this that while del removes by index number,
+`remove` removes on the basis of content being passed on. For instance
+if ::
+       
+       k = [1,2,1,3] 
+       del([k[2])
+
+gives us [1,2,3]. ::
+
+      k.remove(x[2])
+
+will give us [2,1,3]. Since it deletes the first occurence of what is
+returned by x[2] which is 1.      
+
+
+
+
+
+
+
+.. #[[Anoop: does it have two spams or two pythons?]]
+
+.. #[[Anoop: there are no exercises/solved problems in this script,
+   add them]]
+
+Following are  exercises that you must do. 
+
+%% %% Remove the third element from the list, listinlist.   
+
+%% %% Remove 'and' from the list, listinlist.
+
+Please, pause the video here. Do the exercise and then continue.
