Development Readiness (python comes with a virtual environment)

• Create a project code directory

mkdir -p ~/Code/monkey

• Into the project root directory

cd ~/Code/monkey

• Create a virtual environment named env (Note: Python3 comes pyenv)

python3 -m venv env  

• Activating virtual environment

source env/bin/activate

• Installation project dependencies package

pip install -r requirements.txt
