Python Snippet 01 - Requirements.txt

Recently i needed to get the requirements of my Django project so i could move it to a production server.
 So i researched the web and found REQUIREMENTS.TXT

Why requirements.txt?

Any application typically has a set of dependencies that are required for that application to work. The requirements file is a way to specify and install specific set of package dependencies at once.
Format for requirements file: 
Django ==0.10.1
djangorestframework ==1.2.0

Method 1: 

$ pip freeze > requirements.txt
Use pip’s freeze command to generate a requirements.txt file for your project: If you save this in requirements.txt, then you can

$ pip install -r requirements.txt
to install all the requirements of your project.
NB: Use the pip freeze command in your virtualenv or else yuou will list all your dependencies
