To understand what Django actually is for, we need a closer look at the servers. First thing is that the server needs to know, that you want it to serve you a webpage.

Imagine a mailbox (port) which is monitored for incoming letters (requests). It is done by a web server. The web server also sends the response with webpage. But when you want something to send, you need to have some content. And Django is something that helps you create the content.

When request comes to a web server it passes it to Django. Django tries to figure out what actually is requested. It takes a webpage address used and tries to figure out what to. This part is done by Django's urlresolver (Note that a website address is called URL - Uniform Resource Locator, so the name 'urlresolver' makes sense). It is not very smart here - it takes a list of patterns and tries to match the URL. Django checks patterns from top to the bottom and if something is matched then Django passes the request to the associated function called view.

Imagine a postman with a letter who is walking down the street and checks each house number with the one on the letter. If it matches, they put the letter there.

In 'view' all interesting things are done: we can look at the database to look for some information to return it to user. Maybe user asked to change something in the data? Like a letter saying "Please change description of my job title." - view can check if you are allowed to do that, then update the job title for you and send back a message: "Done!". Then view is generating a response and Django can send it back to web server.

Of course, the description above is a little bit simplified, but you don't need to know all the technical things yet. Knowing a general idea is enough.

So instead of diving too much into details, we will simply start creating something with Django and we will learn all important parts on the way!

Django is written in Python. We need it to do anything in Django. Let's start with installing it!

You can download Python for Windows from website https://www.python.org/download/releases/3.4.0/. After downloading ***.msi** file, you should execute it (double-click on it) and follow the instructions there. It is important to remember the path (the folder) where we installed the Python. It will be needed later.

It is very probable, that you already have Python installed out of the box. To check if you have it installed (and which version it is), you type in a console:

$ python --version

Python 3.4.0

If you don't have Python instaled or you want different version, you can install it as follows.

You type in the console:

sudo apt-get install python3.4

Yout type in the console:

sudo yum install python3.4

You need to go to the website https://www.python.org/download/releases/3.4.0/ and install the appropriate package for you operating system.

If you have any doubts or something went wrong and you have no idea what to do next - please ask your coach! Sometimes things are not going smoothly and it's better to ask for help someone with more experience.
