The proyect consist in building a command interpreter, which is the first step towards building a full web application, an AirBnB clone. This back-end console of the website, will allow the user to:
- Create a new object (ex: a new User or a new Place)
- Retrieve an object from a file, a database etc…
- Do operations on objects (count, compute stats, etc…)
- Update attributes of an object
- Destroy an object
To launch the console application in interactive mode simply run:
./console.py
or to use the non-interactive mode run:
echo "your-command-goes-here" | ./console.py
