First step: Write a command interpreter to manage your AirBnB objects.

This is the first step towards building your first full web application:

the AirBnB clone. Each task is linked and will help you to:

• Put in place a parent class (called BaseModel) to take care of the initialize

• Create a simple flow of serialization/deserialization

• Create all classes used for AirBnB that inherit from BaseModel

• Create the first abstracted storage engine of the project: File storage.

• Create all unittests to validate all our classes and storage engine

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

At the end of this project, you are expected to be able to explain to anyone,

without the help of Google:

##General

• 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
:) help

Documented commands (type help <topic>):
========================================
EOF help quit

:)
:)
:) quit
$

But also in non-interactive mode: (like the Shell project in C)

$ echo "help" | ./console.py

:)

Documented commands (type help <topic>):
========================================

EOF help quit
:)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
:)


Documented commands (type help <topic>):
