🧑‍💻 AirBnB clone - The console

Learning Objectives

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 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

Requirements

General

Allowed editors: vi, vim, emacs
All your files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5)
All your files should end with a new line
The first line of all your files should be exactly #!/usr/bin/python3
A README.md file, at the root of the folder of the project, is mandatory
Your code should use the pycodestyle (version 2.8.*)
All your files must be executable
The length of your files will be tested using wc
All your modules should have a documentation (python3 -c 'print(import("my_module").doc)')
All your classes should have a documentation (python3 -c 'print(import("my_module").MyClass.doc)')
All your functions (inside and outside a class) should have a documentation (python3 -c 'print(import("my_module").my_function.doc)' and python3 -c 'print(import("my_module").MyClass.my_function.doc)')
A documentation is not a simple word, it’s a real sentence explaining what’s the purpose of the module, class or method (the length of it will be verified)

Examples to use the console.py by class name

In this section, the operation of the console will be shown by calling each method with the respective class.

How to use:

Retrieve all instances of a class by using: <class name>.all()
Retrieve the number of instances of a class: <class name>.count()
Retrieve an instance based on its ID: <class name>.show(<id>)
Destroy an instance based on his ID: <class name>.destroy(<id>)
Update an instance based on his ID: <class name>.update(<id>, <attribute name>, <attribute value>)
