Setting up a virtual environment

1. Install virtualenv

pip install virtualenv

2. Create and move into the project directory

mkdir projectA
cd projectA

3. Activate the virtual environment (for linux)

source env/bin/activate

4. Verify whether the virtual environment is created successfully

pip list

This will list all the dependencies of the virtual environment

Congratulations you have isolated application dependencies from the system dependencies!

Creating a requirements file

pip freeze > requirements.txt

This will list all the dependencies of the application, which can be used to replicate across different systems

Creating an environment file to store secrets or configuration information

DB_USERNAME = 'your_db_username'
DB_PASSWORD = 'your_db_password'
DB_NAME = 'you_db_name'

5. Exit the nano editor

ctrl + s and ctrl + x

6. Add a .gitignore file
