2.    Run gedit so we can fix few default setting:

             2.1 Open  'edit>preferences' select the 'editor' tab

             2.2 Changed tab width to 4

             2.3 Select 'insert spaces instead of tabs'

             2.4 Turn on “automatic indentation” as well

             2.5 Now, view tab turn on “display line numbers”.

3.    Open your 'Terminal program', run python.

◦     If you run python and its not there, install 'python 2' not 'python 3'.

◦     Type 'exit()' or 'ctrl+d' and get out of python.

Note :

  1.    Use gedit because it is simple and same on all computer/environment.

  2.    Never use 'Vim' or 'Emacs' these are for a better programmer.

What is Ajax

The standard model for Web applications is something like this: you get a screenful of text and fields from a server, you fill in some fields, and when you click a button, the browser sends the data you typed to a server (wait), which processes it (wait), and sends back an answer (wait), which your browser displays, and then the cycle restarts. This is by far the most common way Web applications operate, and you must get used to the delays. Nothing happens immediately, because every answer that needs data from a server requires a round trip.

            

               AJAX (Asynchronous JavaScript And XML) is a technique that lets a Web application communicate in the back-ground (asynchronously) with a Web server to exchange (send or receive) data with it. This does away with the requirement to reload the whole page after every action or user click. Thus, using AJAX increases the level of inter-action, does away with waiting for pages to reload and allows for enhanced functionality. A well-programmed application will send requests in the background, as you are doing other things, so you won’t have to stare at a blank screen or a turning-hourglass cursor. This is the Asynchronous part of AJAX acronym.

                 The next part of the AJAX acronym is JavaScript. JavaScript allows a Web page to contain a program, and this program is what allows the Web page to connect to a server as previously described. However, it’s not just a question of having JavaScript, but also of how it is implemented in the browser. Both Firefox and Internet Explorer both provide AJAX access, but with some differences, so programmers must take those differences into account when doing the connection. Data is usually retrieved using XMLHttpRequest, but other techniques are possible, such as using iframes. 

                    last part of the AJAX acronym is XML. XML is a standard markup language, used for sharing and passing information. As we’ve seen, the name of the DOM API for making Web service requests is named XMLHttpRequest, and most likely, the original intent was that XML be used as the protocol for exchanging data between browser and server. However, neither the X in AJAX nor the XML in XMLHttpRequest means that you have to use XML; any data protocol at all, including no protocol, can be used.

             JSON (JavaScript Object Notation) often is used; it’s more lightweight than XML, and as you might guess by its name, is often a better fit for JavaScript. See Figure 3 for some actual JSON code; remember, it’s not meant to be clear to humans, but compact and easy to understand for machines. AJAX comprises basic technologies that have been around for a while now, and the AJAX term itself was created in 2005 by Jesse Garrett. GWT uses AJAX to allow the client program to communicate with the server or execute procedures on it in a fully transparent way. Of course, you also can use AJAX explicitly for any special purposes you might have.
