AirBnB clone - The console

Is a command interpreter and the main purpose is to manage, manipulate and access the data in the backend through the console (command line tool ) very quickly and easily (like in shell project).

• We’ll manipulate data with JSON serialization/Deserialization (First DB engine).
• Manipulate Python packages
• Implement cmd module
• Implement uuid module
• args/kwargs
• datetime
