  - Install Python packages from PyPI
   
Demonstration [02:00 | 03:27]
----------------

**Working with virtual environments**
  - Creating a virtual environment in Python 3
    - *python3 -m venv myapp_env*
  - Activate the environment
    - *source myapp_env/bin/activate*
    - Shell prompt will be *(myapp_env)user1:~$*
  - Deactivate the environment
    - deactivate
    
Demonstration [02:00 | 05:27]
---------------

**Install Django**
  - Let us reactivate the virtual environment
    - *source myapp_env/bin/activate*
  - Check if django is installed using;
    - Command: *python -m django --version*
    - If not installed then we see "No module named django"
  - pip install django
  - Again we check and now we see the django version
  - We can also update the django version in future
    - pip install -U django
  - For more help:
    - pip --help or pip <command> --help

Demonstration [ 02:30 | 07:57]
---------------
- Now we will run few commands to see how django works.
- We will learn about them in later tutorials.
- Type the following command:
  - django-admin.py startproject demo-project
- This creates a project directory with all the necessary files.
- cd demo-project
- Now run:
   - python manage.py runserver
- This may give migrations warning at the start, we ignore them for now.
- We see that the server is running now.
- Go to the address shown, mostly will be http://127.0.0.1:8000/
- So in a web browser we see the django index page.
- Go back to the terminal.
- We can quit the server with CONTROL-C
- You can also delete the virtual environment by deleting it's directory
  - *rm -rf myapp_env*
