+
+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
+
+.. #[Nishanth]: Did you compile this??
+ There must an empty before the bulleted list
+
+I hope you have ipython running on your system.
+
+.. #[Nishanth]: need not specify. Implicit that IPython is running
+
+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.
+
+.. #[Nishanth]: do not use "You" or anything else. Stick to "We"
+
+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 being the last element , -2 second to last and -4 being the first
+element.
+
+.. #[Nishanth]: -1 being last element sounds like -1 is the last element
+ Instead say -1 gives the last element which is 4
+
+.. #[Nishanth]: Instead of saying -4 being the first, say -4 gives 4th
+ from the last which is the first element.
+
+* =append= elements
+We can append elements to the end of a list using append command. ::
+
+ nonempty.append('onemore')
+ nonempty.append(6)
+ nonempty
+
+As we can see non empty appends 'onemore' and 6 at the end.
+
+.. #[Nishanth]: First show an example with only one append.
+ may be show the value of a after first append
+ then show what happens after second append
+
+Using len function we can check the number of elements in the list
+nonempty. Because we just appended two elements at the end this
+returns us 6.::
+
+ len(nonempty)
+
+.. #[Nishanth]: the "because ..." can be removed. You can simply
+ say len gives the no.of elements which is 6 here
+
+Just like we can append elements to a list we can also remove them.
+There are two ways of doing. One is by using index. ::
+
+ del(nonempty[1])
+
+.. #[Nishanth]: do not use "You" or anything else. Stick to We
+
+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.
+
+
+{{{Slide for Summary }}}
+
+
+In this tutorial we came across a sequence data type called lists. ::
+
+ * We learned how to create lists.
+ * Append elements to list.
+ * Delete Element from list.
+ * And Checking list length.
+
+.. #[Nishanth]: See the diff. I have corrected punctuation in many places.
+ The first thing you do before committing is compile the script.
+ I have corrected syntax errors also in many places.
