-Hello friends and welcome to the tutorial on getting started with
-lists.
-
- {{{ Show the slide containing title }}}
-
- {{{ 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
- * Deleting elements from lists
-
-List is a compound data type, it can contain data of other data
-types. List is also a sequence data type, all the elements are in
-order and there order has a meaning.
-
-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.
-
-* Filled lists
-
-Lets now define a list, nonempty and fill it with some random elements.
-
-nonempty = ['spam', 'eggs', 100, 1.234]
-
-Thus the simplest way of creating a list is typing out a sequence 
-of comma-separated values (items) between square brackets. 
-All the list items need not have the same data type.
-
-
-
-As we can see lists can contain different kinds of data. In the
-previous example 'spam' and 'eggs' are strings and 100 and 1.234
-integer and float. Thus we can put elements of heterogenous types in
-lists. Thus list themselves can be one of the element types possible
-in lists. Thus lists can also contain other lists.  Example ::
-
-      list_in_list=[[4,2,3,4],'and', 1, 2, 3, 4]
-
-We access list elements using the number of index. The
-index begins from 0. So for 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]
-
-We can also access the elememts from the end using negative indices ::
-   
-   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 last element which is first element.
-
-We can append elements to the end of a list using append command. ::
-
-   nonempty.append('onemore') 
-   nonempty
-   nonempty.append(6) 
-   nonempty
-   
-As we can see non empty appends 'onemore' and 6 at the end.
-
-
-
-Using len function we can check the number of elements in the list
-nonempty. In this case it being 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
-should be :: 
-      
-      a.remove(100)
-
-but what if their were two 100's. To check that lets do a small
-experiment. ::
-
-	   a.append('spam') 
-	   a 
-	   a.remove('spam') 
-	   a
-
-If we check a now we will see that the first occurence 'spam' is removed
-thus remove removes the first occurence of the element in the sequence
-and leaves others untouched.
