Welcome to the AirBnB clone project! (The Holberton B&B)
What’s a command interpreter? Do you remember the Shell? It’s exactly the same but limited to a specific use-case. In our case, we want to be able to manage the objects of our project:
- 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
- How to create a Python package
- How to create a command interpreter in Python using the cmd module
- What is Unit testing and how to implement it in a large project
- How to serialize and deserialize a Class
- How to write and read a JSON file
- How to manage datetime
- What is an UUID
- What is *args and how to use it
- What is **kwargs and how to use it
- How to handle named arguments in a function
Your shell should work like this in interactive mode:
$ ./console.py
(hbnb) help
Documented commands (type help <topic>):
========================================
EOF help quit
(hbnb)
(hbnb)
(hbnb) quit
$
But also in a non-interactive mode: (like the shell project in C)
$ echo "help" | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF help quit
(hbnb)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF help quit
(hbnb)
$
Launching the console
$ ./console.py
