Slide: Getting started with Django	Hello and welcome to the spoken tutorial on “Getting started with Django”
Slide: Learning Objectives	In this tutorial, we will learn About Python Virtual Environment How to use the Virtual Environment How to install Django How to start a Django project and The Django project file structure
Slide:System Requirements	To record this tutorial, I am using Ubuntu Linux 16.04 Python 3.5 Python 3.4-venv or higher and Firefox web browser. However you may use any other browser of your choice.
Slide:Python Virtual Environment	* Python virtual environment is an isolated working copy of Python virtualenv is a tool to create an isolated Python environment It allows us to work on a specific Django project without affecting other projects It does not require root access
Slide: pip	* One can install, upgrade and remove Python packages using a program called pip By default, pip will install packages from the Python Package Index https://pypi.python.org/pypi
Open a terminal window Press CTRl+ALT+T	Open the Terminal by pressing Ctrl, Alt and T keys together.
[Terminal]	Let me create a folder named my-django. This folder will help me to organize my files in a single location on my machine.
[Terminal] Type mkdir my-django Press Enter	To do so, type mkdir <space> my <hyphen> django and press Enter.
[Terminal] Type cd my-django and press Enter	Then type cd <space> my hyphen django and press Enter.
[Terminal] Type python3 -m venv myapp_env	Let us now create a new virtual environment named myapp underscore env. Type python three <space> hyphen m <space> venv <space> myapp underscore env
[Terminal] Highlight -m Highlight venv	hyphen m option is used to pass the python module as a command line argument. Here venv is the python module. The given module is executed as a script.
Press Enter	Now press Enter.
[Terminal] Type ls	Type ls and press Enter. We can see that a directory named myapp underscore env has been created.
[Terminal] Type ls myapp_env and press Enter	Type ls <space> myapp underscore env and press Enter.
[Terminal] Point to the list of directories in the terminal	We see that the virtual environment contains various directories.
[Terminal] Point to bin	bin contains executable files.
[Terminal] Point to lib ls <YOUR_PATH TO site-packages>	lib contains supporting library files. Packages installed in this environment will be in site-packages.
[Terminal] Type: source myapp_env/bin/activate and press Enter	Let us now activate the virtual environment: Type source <space> myapp underscore env slash bin slash activate And press Enter.
[Terminal] Highlight (myapp_env)	So, the virtual environment is active now. We can see an additional text in the command prompt. It shows the virtual environment we are using - that is myapp underscore env.
[Terminal] Type python -m django --version and press Enter	Now, let's learn how to install Django. First, let’s check whether Django is already installed on our system or not. To do so type python <space> hyphen m <space> django <space> hyphen hyphen ­version And press Enter.
[Terminal] Point to the error message	Obviously it is not installed in this Virtual Environment. So we will see an error message No module named django.
[Terminal] Type pip install django==2.0 and press Enter	In the new environment, we will use pip to install Django. First let me clear the terminal by pressing Ctrl and L keys Type pip <space> install <space> django <equal to equal to>2.0 We will use Django version 2.0 If we don’t mention <equal to equal to> 2.0 then the latest stable Django version will be installed. Press Enter. The installation may take some time depends upon your internet speed.
[Terminal] Type python -m django --version and press Enter	Now, let us check whether the installation has been successful. Clear the terminal. Type python <space> hyphen m <space> django <space> hyphen hyphen version And press Enter.
[Terminal] Point to the output	The terminal output displays Django version 2.0 here. This indicates that the Django package has been installed.
[Terminal] Using command: pip install -U django	We can also update the Django version in the future using the command: pip <space> install <space> hyphen U <space> django
[Terminal] Type pip --help or pip --help and press Enter	For more help on pip: Type pip <space> hyphen hyphen help And press Enter.
[Terminal] Type django-admin startproject mysite and press Enter	Next we will create a Django project named mysite. In the terminal, type: django hyphen admin <space> startproject <space> mysite And press Enter.
[Terminal] Type ls and press Enter	Type ls and press Enter. We can see the project directory mysite. Let us now see the project file structure.
Switch to Slide Slide: What is a Django project?	Before that we will understand what a Django project is. A Django project is a collection of Settings for an instance of Django Database configuration Django specific options and Application specific settings
Slide: File structure mysite/ manage.py mysite/ _init_.py settings.py urls.py wsgi.py	The startproject command creates a project consisting of a file structure as shown here.
[Terminal]	Switch back to the terminal.
[Terminal] Type cd mysite and press Enter	Now type cd <space> mysite and press Enter. We are inside the mysite directory.
[Terminal] Type ls and press Enter	Type ls and press Enter to list the contents.
Highlight the mysite file structure in the terminal	Here we can see that the mysite file structure has been created.
[Terminal] point to ~/myproject/mysite$	The outer mysite is just a container of our project.
[Terminal] Point to manage.py	manage.py is a command line utility to interact with our Django project.
[Terminal] Point to inner mysite	The inner mysite is the actual Python package for our project.
[Terminal] Type ls mysite and press Enter	Now, type ls space mysite and press Enter.
[Terminal] Point to __init__.py	We see init dot py That means the mysite directory contains python packages.
[Terminal] Point to settings.py	settings.py file contains all the configuration of our Django project.
[Terminal] Point to urls.py	urls.py contains URL declarations for this project.
[Terminal] Point to wsgi.py	wsgi.py is an entry-point for web servers to serve our project.
[Terminal] Run the project	Next, let's see how to start the Django development server.
[Terminal] Type python manage.py runserver and press Enter	Type python <space> manage dot py <space> runserver And press Enter.
[Terminal] Point to shell prompt	We can see that the server is running.
Open a browser and type http://localhost:8000/	Next, open a web browser. In the address bar, type http://localhost:8000/ or http://127.0.0.1:8000/ And press Enter.
Point to the Django index page	In the web browser, we see the Django index page.
Switch to Terminal	Let us go back to the terminal.
Press Ctrl+c simultaneously	To stop the server, press Ctrl and C keys simultaneously.
[Terminal] Type deactivate and press Enter	When the virtual environment is not in use, we can deactivate it. To do so, type deactivate and press Enter.
[Terminal] Point the shell prompt	We can see that, the virtual environment name disappears from the command prompt.
Switch to Slide Slide: Delete the virtual environment	If the virtual environment is no longer needed, we can delete it. This is done by deleting its directory. The command is rm <space> hyphen rf <space> myapp underscore env
Only narration	For now, we will not delete. We will keep the virtual environment for creating the Django project in the upcoming tutorials.
	With this, we come to the end of this tutorial. Let us summarize.
Slide:Summary	In this tutorial, we have learnt - About Python Virtual Environment How to use the Virtual Environment How to install Django How to start a Django project and The Django project file structure
