This is the first step towards building our first full web application: the AirBnB clone. This first step is very important because we have to use what you build during this project with all other following projects: HTML/CSS templating, database storage, API, front-end integration…
- put in place a parent class (called BaseModel) to take care of the initialization, serialization and deserialization of your future instances
- create a simple flow of serialization/deserialization: Instance <-> Dictionary <-> JSON string <-> file
- create all classes used for AirBnB (User, State, City, Place…) 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.
A command interpreter is a customized console design by me to manipulate our python objects linked to our storage system.
- 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 handle named arguments in a function
- 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**8("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)
